Hey all: I have an audio signal from an old portable CD player that on max volume outputs about 1-1.2V as shown when attached an oscilloscope. I want to feed this signal into a PIC microcontroller, but I hear you need to amplify and shift the signal into the 0V to +5V region for it to work...

Thank you very much for the reply. What keywords do you think would be good. Like the topic and stuff like that?

Hey all: I know the best way to learn mathematics is by practicing questions and just do them over and over again. I find a lot of the time, the assigned questions just aren't enough for most courses. I was wondering if there was a repository or aggregate site online that contains a lot of...

Thanks again. But I tried that and I get a different temperature for the bottom and the sides/top since the temperatures are different. All I know is that QTOTAL = QSIDES + QTOP + QBOTTOM = 200W. I know there is a temperature in there somewhere but I don't know hoe to extract it. Sorry if I...

How would you go about finding RTOTAL? Would you just add up all the Rs and also, would you multiply the RSIDES by 4 since there are 4 sides? Thanks!

Hey all: I am taking a Thermodynamics course and we are studying work and heat through surfaces (i.e. conduction, convection, and radiation). I was given an assignment and I am having trouble arriving at the correct answer. I have scanned the question and the works I have so far. I hope...

I would also be interested in something like this. Thanks!

Yeah. That is pretty much what I wanted to, but I wanted the signal conditioning outside of the chip. So pretty much I want. Sensor input > signal conditioning > ADC > micro-controller Thanks for the input!

Hello all: This is my first post on the physics forum so I am excited to have found such a great community of scientists. My problem is that I have been looking for an embedded board that contains an ADC but has a very good external signal conditioning stage. This will be for a data...
