Hello, My dvd player just bombed out on me and I am deciding whether or not to buy a new dvd player or to set up my laptop to be able to play dvds on my tv. I have a Sony KD32FS130 32" FD Trinitron WEGA Television for your reference. The problem is that my dell notebook only has...

Hello, this is something I am not sure about, so want to make sure before burning my friends electronics :biggrin: . we are trying to use 68hc12 for processing a sensor input, but the signal from the sensor comes out to be more than 5 volts (around 15 or 20 v), so what we need is to scale the...

I am trying to design a 3 1/2 digit 20V voltmeter using the ICL7106 and I was wondering if anybody could help me with a few things: 1. How could I get it callibrated to a max 20V reading? 2. I will be using it as an onboard voltmeter for a variable DC power supply. If I tap the source 18V...

cin or scanf? i use cin from iostream.h in c++ i also knowabout scanf in stdio.h but which is better? What is the difference betweeen the both? -benny

Hello, I am doing a senior design project on converting corn into ethanol. I would like to perform my mass and energy balances on hysys. However, HYSYS does not have glucose and many other streams of substances that would be flowing through our process. Is there a method to input new...

I have a simple statics problem that I am trying to solve. The rigid body to be analyzed is an upside down L-shaped beam connected together at the corner by a pin. The object has a height of 4.5 meters vertically, by 3.5 meters in the horizontal. Additionally, the object is secured to the ground...

I'm trying to model a circuit. Part of this circuit is a guitar amplifier. I don't know what kind of circuitry is inside the guitar amp, it manufactures often list the input impedance in the product specifications. When they say input impedance, do they mean the impedance between the...

Hey guys, I'd like to build a 400W powered amplifier for small signal input from a microphone source to amplify vocals out of PA speakers. I have found the following schematic and I have two questions for whomever is willing to help: 1) Is this circuit adequate for the application? 2)...

1-How could an RL combination be connected to produce an output voltage which is the time derivative of the input voltage? 2-Show that taking the time derivative of a sinusoidal function [such as cos(wt+a)] always has the effecton increasing its phase pi/2. 3-İf the internal series...

y`` +y`+y=r(t) why's r(t) the input and not t?

http://img420.imageshack.us/img420/9300/img02643tt.jpg hello this is the problem i am working on. i started out by using the admittance parameter equation i1 = y11*v1 + y12*v2 i2 = y21*v1 + y22*v2 so i1 is 20/50 by ohms law. so i1 = 0.4 so by the first equation i get v2 = 32 V. also...

Hello everyone, I'm confused on what they want me to do here: it says: Find a minimum gate input count realization of the enabling logic using AND and OR gates and inverters. Well This is my truth table i came up with, and the "enabler" is the M, the master switch( 0 secruit system on, 1...

are the input impedances for both inverting and non-inverting amplifiers infinity?

I have a USB Iomega zip drive (100MB) that uses both an external power supply and USB cable. Subsequent models of the same drive take power (5V) directly off the USB from the PC. I wish to modify my zip drive to make it a bus-powered device. The external PS measures +5V open circuit. The spec...

There are a few things that I can't remember learning in my Computer Programming class, and I haven't been able to find the answers. Can anyone tell me how to: -round a number to a certain number of decimal places? -use dates (month day, year) as response to input as a single variable...

what would happen if u input a signal into an output pin of a chip?

The only good way to gather user input in games and other real-time applications in Windows that I know if is to use Direct X. I really hate using OS-specific APIs and libraries. Is there any sort of platform-independent input library out there that does a decent job of giving the programmer...

lm doing an assignment regarding resistance may caused an error in the magnitude of the output voltage.

Well like the title says I'm buying a new telescope and would like to know what y'all think would be the best for looking at Galaxies and Nebulas, PRICE IS NOT A PROBLEM though I would like to keep it lower then $3,500.

I've just started a linguistics book, and I'd like to get others' opinions on two points that I have reservations about. I get the sense that they may be overstating things a bit in trying to make the case for Universal Grammar. I was going to let this go, but they bring it up elsewhere too...

Hi I need to "plot the output response of the system shown to the input stimulus given" I suppose it would help if i knew where to start, but I'll try and explain as best I can. There are two drawings. Drawing 1 - shows a rectangle with 1 / 1 +0.5s inside and a line drawn...

In a welding process,i am welding two plates. The welding current is 110A and welding voltage is 20V. Suppose 100% of this electric energy is converted to heat then the heat energy generated is 110x20. i.e., 2.2KJ/sec. Suppose the length of the plate is 2 metres, How can i calculate what is...

Hi, if anyone has successfully done an egg project like this, I would really appreciate any input. The thread is in the general engineering section. thanks

Can anyone figure out the input impedance of the circuit I have attached? Does anyone know a THOROUGH definition of input impedance? output impedance? Output impedance is equivalent to the thevenin impedance, which mean we turn off all voltage/current sources. But for input impedance...

I have been having a discussion with a friend for the past few days, and we are in sort of a stand still on a problem. We would greatly appreciate some input into our discussion. The question is this: A hollow spherical object weighs ten pounds with a certain density, and size floats in...

is there such a thing as what's mentioned in the subject heading? Preferably a small device would be wanted... Thanx!

Here's my problem: For each kW of power input to an icemaker at steady state, determine the maximum rate that ice can be produced in kg/h, from liquid water at 0 C. Assume that 333 kJ/kg of energy must be removed by heat transfer to freeze water at 0 C, and that the surroundings are at 20 C...

Hi, I'm trying to convert a 3 input OR gate using only 2 input OR gates . How exactly will this look like? Thanks

okay, I Don't quite grasp this concept but!. Vo/Vi = No/Ni. And I have this problem. A Generator at a power plant produces AC at 24,000 V.A transformer steps this up to 345,000 V for transmission over power lines. IF there are 2000 turns of wire in the input coil of the transformer, how many...

A straight horizontal pipe with a diameter of 1.0 cm and a length of 50 m carries oil with a coefficient of viscosity of 0.12 N · s/m2. At the output of the pipe, the flow rate is 9.0 10-5 m3/s and the pressure is 1.0 atmosphere. Find the gauge pressure at the pipe input I used the formula...

Ok, Currently I'm enrolled in a phyics based major, at an Ohio university. I'm thinking about transfering in about a year or two to a engineering school. I love working with anything airplane related, and i have a natural nact for that stuff as well. I was looking at an AE program but they deal...

Hello, I am exactly half-way through a degree in engineering physics. At my school, most students are either in the engineering physics program or the aerospace engineering program. Up to the half-way point (where I am now), both programs are almost identical. I don't really want to...

GO to This post And watch this video. You'll need realplayer which can be obtained at www.realone.com I won't make any further comments because I would like people's unbiased opinions on what amounts to a conference and presentation to various congressman and press. I welcome any and all...

A heat engine has efficiency of 30% and its power is 600W. what is the rate of heat input? is 1.8Kw right? e=W/q_h .30 * 600 TY dx:wink:

I have a few questions that i need help understanding how to answer: 1. At a power plant, the operating temperatures are 700 C and 310 C. The efficiency of the plant is 65% of its Carnot efficiency. The output of the plant is 500 MW. a. Determine the efficiency of the plant. b. What is the...
