I know this may seem like a simple question to some of you experts out there, but I was thinking today about how much computers have advanced and how they allow us to make substantial progress in design and simulations and stuff. Actually, what got me thinking about it was in my propulsion book...

Determine if the CT systems are 1) casual or uncasual 2) memory or memoryless. [SIZE="1"][SIZE="2"]Definitions: Casual: If for any time t1, the output response y(t1) at time t1 resulting from input x(t) does not depend on the values of the input x(t) for t > t1. Memory: If the output at...

I need help, pls ! Hello, Could you pls help me answer this question: - Please take a look at my small Assembly program that reads a tring from keyboard, then displays all the characters that are not uper-case letters in reverse order: .model small .stack 100 .data tb1 db 'Pls enter a...

OK, so this isn't anything I've ever done before and would like some input on feasibility, and whatever else you can throw at me. I'm examining images (of atmosphere with a storm structure building up) but unfortunately the data that is available (i.e. the data I've got to use) has quite...

Hi,I am a graduate student, want to transfer from physics to electrical engineering to study communication and digital signal processing , till now I don't know so much about that. Next semester, I will be a Teaching Assistant in Electrical engineering for the first year.each semester I must...

I have a huge set of data. About 5000 excel sheets and in each one about a 500x7 matrix. I'll be doing a lot of manipulation where I'll need a programming environment that is faster than excel (excel is pretty slow). Anyone have experience with both R and Matlab and can comment on which one is...

Hey guys, I am using the sptool GUI to design and apply filters to noisy ECG signals. I understand the concepts behind lowpass, highpass, and bandpass filters. But I'm confused with the parameters of FDA tool. Here are my questions: 1) In the FDA tool, there is a bandstop filter. what is...

Would a analogue processor offer significant speed ups on binary processors, on the scales of decimal bits and then if we had a bit with 100 states. I know that for the transfer of information would receive significant improvements but would this also be true for processing information?

[Note: P and p throughout are probabilities] Fact: The hypergeometric distribution is the precise probability of crawing from a dichotomous (S-F) population without replacement. A family of probabilistic sieves can be constructed using this fact as follows. Step 1: Suppose we know all...

hello everyone, what stuff can i tackle on my own to learn dsp? complex variables and Fourier transforms to begin with - but what else? how do other aspects of EE play into dsp? how do i get functionality fastest!?

How many cubic centimeters of ore 0.25% by mass silver must be processed to obtain 2.0 pounds of silver? The density of the ore is 7.0 g/cm cubed. cm cubed; 1.00 pound=454 g. Assume that the process is 100% efficient. I get the answer of 520 but the answer is 52000 and i don't understand why...

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 interested in DSP, for the coming semester, I can only take one signal processing class, and I have two choices that I am not exactly sure what they really are: 1) Statistical Signal Processing: Detection theory and hypothesis testing. Introduction to estimation theory. Properties of...

Hi I've just got a small problem that needs to be cleared here to allow me to do the other questions. Statement: Two objects were detected in a 100-sec exposure with 3x4 CCD camera Now you are given 3 by 4 matrices for the raw image data, bias, dark count and flat field. I've provided a link...

anyone know of any forums discussing abt above issues?

I want to write a program in Java that reads RGB information pixel-by-pixel from an image file, processes that information, and then writes it to a text file. I know how to do everything except read from the image file. I'm thinking a Bitmap file might be the best choice for the image file...

I have been reading about the new cell processing that would be used for the PS3. I was wondering when it would be available for regular computers and what price range you think it would be in. I was hoping to build a very nice computer before I go off to college next year, but I am kind of...

Hi. I have a data gaussian g(t) and data that I suspect is a convolution (g*f). I want to find f(t), so I need to deconvolute (using Origin preferably). If I convolute g*g, I get something very beautiful. If I convolute (g*f)*(g*f), I get something very beautiful. If I deconvolute...

My academic background is in math and linguistics, but lately I've gotten interested in speech processing. What I'm wondering is whether I need to go back and get a BSEE (and possibly an MSEE or PhD in EE) or if I can realistically hope to get into the field by just taking a few courses in...

Hi, I was just wondering if anyone has any experience with signal processing. I am working with musical instrument recognition and would like some help. What is the main difference between musical instrument signals? Where can I get some resources on signal processing(I am using Matlab, but...

It's common knowlegde that any traditional logic function can be realized using quantum logic gates (gates that are reversible). I've been looking for a good book on the subject of Quantum Information Processing but I haven't found one that I am willing to shell out the money for at this point...
