During high school I build a simple circuit powered with 9V battery. This circuit is unique because it convert analog signal to digital. When this signal is being outputed to speaker, the speaker will convert it to analog again. I remember having better treble using this configuration.
The circuit convert amplitude into duty cycle.
I remember the circuit is simple, maybe only two chip. If I am not mistaken, it is from 301 electronic book. Unfortunately I lost it. Anyone know this circuit?
The reason I ask this in this forum is because I want to use it for experiment on radiant oscillator. It would be interesting if our transformer sing our favorite song instead of monotone note. Maybe anyone with tesla transformer can help, I read that some people use it to make spark gap as speaker.
I want to convert amplitude into OFF signal time. ON signal time is fixed.
Thanks in advance.
