There's probably nothing anyone can do to help me, so this is mostly a *****, but I have a Nikon Coolpix 3100, which is a great camera except for the battery life. Now, I know most digital cameras have crappy battery life, but mine is rediculous. What makes me think something can be done about...

hi, a friend is heading over to malaysia in the next few days and asked me if i wanted a 10000rpm ( 8mb cache, SATA ) 74 GB WESTERN DIGITAL 10000RPM hard disk. i would say yes but i am not sure if it will work on my pc my motherboard is an ASUS P4P800SE with Intel 865PE Chipset can someone...

Digital Electronics Boolean Reduction! Help Please Ok i need to figure out how to reduce this I've been working on it for 2 days straight and can't figure it out...please help...its due tommorow :rolleyes: :cry: (ab)(\overline c + \overline d)+(a+b)(\overline c \overline d)

Discuss the differences between digital and non-digital communication. the conventions of both must be demonstrated using examples. Terminology must be employed correctly throughout... -- I have gathered research about the difference between analogue and digital, however I cannot think of...

I use a digital pedometer which has pace counting gigure. Four items are displayed: Pace number , pace number by mile, kilometer as well as consumed calories. I need help in finding out : 1. What is the relationship between distance in kilometers and calories burnt? 2.While the pedometer...

Just wondering if anyone else is participating in the http://www.worldofwarcraft.com/ http://www.worldofwarcraft.com/misc/openbeta-faq.html? I have sunk more hours than I care to admit into it this weekend. The game is amazing. Warning: If you are a video game addict, do not download it, or...

Digital and Analogue Signals... When learning about digital and analogue signals, I have been told that a fibre optic cable can be used for digital signals, whilst a copper wire is usual used in the case of anaolgue elctrical signals. My question is could they be used for the other things? Ie -...

Hi, I'm trying to design a low-cost digital radio interface to communicate with a robot. I'm not interested in exchanging a lot of data, or doing it at high speeds. This design will work well if I can get even 300 baud out of it since I never exchange more than about 1K bytes during a...

from analog to digital(PCM/QAM) I want to convert analog to digital. I am recording analog signals in my firm and i want to make a programm witch helps me to decode fax informations. if you know how to decode this analog signals witch is modulated with PCM/QAM, please help me.

[FONT=Verdana]Does anybody have a logical explanation to what those little white things on digital pictures are? I figured they can't be dust on the camera lens because they come out in a different place of the photo even if 2 photos are taken one after each other. Anybody, any ideas?

Hey guys; I'm having an add problem with my digital camera. It's an Olympus C-50 Zoom. I plug it into my USB port, and it says "New Hardware Found", then it shows that it recognizes it as what it is, the digital camera, then it says it found a "USB Mass Storage Device". It shows no errors...

From physics sheet - "all signals (digital a reduction in signal power) as they travel through a system and need amplification at certain intervals." Why is this the case?

My intro to digital system teacher is hard. He gives question that ask u design circuit such as make a counter that count 3 5 9 0 3 using mod-6 counter + encoder + decoder. Do question like this have a systematic way of solving or is only solvable if u have mad experience? He seems to give...

The original handheld calculator. Curta This was designed in Buchenwald, the German concentration camp, the first prototypes built from the original hand drawings worked. It was manufactured from 1948 till ~1970 when cheap electronic calculators came on the market. I would love to hold...

hey guys I am stumped on this project: make a 2 floor elevator. i am going to use an H-bridge to control which way the motor spins (ie. clockwise will make the elevator go up, counter - down). anyway, here are the initial conditions to be met: elevator must stop at both floors elevator will...

I designed an optical A/D (on paper only) several years ago. I have no means to make one since small scale integration is required. Any ideas how to get someone interested? If it works correctly, there would be zero conversion time and only settling time for the detectors outputs.

I originally posted this in the Relativity forum but I thought it was cogent to this topic so I'm repeating it. Sorry for the redundancy: Is the Universe Analog or Digital? First, I'm new to this forum, so I'm sorry if I'm being redundant or naive. Anyway, a while ago, I'd seen the...

First, I'm new to this forum, so I'm sorry if I'm being redundant or naive. Anyway, a while ago, I'd seen the question posed, "Is the universe digital or analog in nature?" Seemed like such a complex question at first, but then I came up with the following answer, and it's not what some...

Digital Camera ! I need to buy a digital camera. And I've budget 200-300 USD. Can you suggest any?

Ok, i learned yesterday that Digital was old fashioned, which does in a way make sense because the waves are very basic (compared to analogue. Also i learned that Digital TV cut out around 95% of the information that would appear on an analogue wave. Instead of focusing on expanding digital...

I'm trying to optimize my digital recording capabilities, and to do so I need to get my hands on a 25 pin scsi card for my pc. I have had no luck trying to find one of these things. Does anyone know of a place I might find one? Also, can a mac scsi card be easily manipulated to work in a pc? Thanks

First, let me introduce the situation: I'm an undergraduate physics major taking a course in Experimental Physics. In the lab I am investigating the motion of natural underdampened oscillators. The oscillators under investigation are nothing more than various pieces of metal suspended...

simple question... do we see in digital or analog?
