can anybody tell me how i can compare two frequncies using beat frequencys???
im trying to make a guitar tuner as my HNC project and im generating a sqaure wave from and oscillator circuit,which im using as a reference frequency to compare with an input from my guitar, which, produces a sinusodual output.
if compare the square and the sinewaves i am not able to turn a bulb(indicator) on and off completly so i do really need two sine waves....
after all that any ideas
