    Amplification to a constant Vpp

    I am working with +/- 12 volts. And yeah, you are right. I don't really need this gain. But for whatever reason I really care to do this. I am just trying to figure out a clever way.

    Amplification to a constant Vpp

    The reason that I want to keep the amplitude constant is that frequency is the only thing that I need from the mic's signal. This is not necessary, but I am also aiming to learn this well.

    Amplification to a constant Vpp

    The sound the microphone receives is a signal whose frequency changes linearly, that is what i meant. Is that called a warble tone ? Anyways, the application has nothing to do with music. The thing works like a radar. You see, after the sound is received from the mic, it will be passed from a...

    Amplification to a constant Vpp

    Hello there! Thank you all for your replies, they provided me with a good starting point. First off, we say piece of cake here too^^ Although as I am on a ... kind of a diet... I've been trying to avoid cake :) I am sorry that I haven't answered already, as this is only a part of a...

    Amplification to a constant Vpp

    Consider this like a voltage regulating circuit. Think of an amplifier where the input is a sinusoidal, perhaps not in the small signal range. And that we want to amplify this signal to a certain Vpp, say for example vpp = 2. To make this a bit clearer, if the input is a sinusoidal with an...

    Efficient Band Pass Filter- Ideas Apperciated

    I am working on something that will require me to perform 3 different actions based on the frequeny of the input signal. I immediately thought of using 3 band pass filters, but turns out they aren't always extremely effective. Any ideas about how to make an efficient band-pass filter? I've...

    Translating Analog Signal into Digital and Displaying it With Led's

    Hello everyone. I am working on a homework project, and at this final stage, this is my situation : I have a circuit where an LM35 chip yields temperature in a voltage rate proportional to the ambient centigrade value (eg. 20 degrees would be 20mV V). Then, after i found out i had to turn this...

    Term Project - Air Conditioner (of Some Sort.) - any aid is welcome.

    To introduce myself, I am a sophomore electrical engineering student.And I am required to design an air conditioner for my term project. Normally this thing is done in groups of two, but my partner is (which i didn't know when i picked him) kind of (absolutely in fact) useless. So now i am stuck...
