that looks like it would be perfect, but the only input I could give it would be pulse train (no negative values) wave, not a full square wave, if i could gain the negative parts back from the pulse train I could use it right?
Thanks for the post!
Basically I am trying to convert an 8-bit binary number to a sinusoidal frequency for a speaker. The ouput from my DAC is from 0v to 5v in steps of around .020v increments and I need to implement sine waves from 200Hz-1000Hz. And I just cant determine how to convert the output voltage to a frequency. If there is an easier way to just control frequency with a voltage that would be ideal.......
I want to input 00000000 and get 200Hz, and 11111111 and get around 1000Hz (or less)
amplitude for the frequency wouldnt really matter in the conversion, i could just put it through an audio op-amp
Thanks for the help
