Hey everyone,
Trying to figure out how to design a signal sampler that will sample a analog input signal (audio signal) and use PAM (pulse amplitude modulation) to sample it from 0-80 kHz. The duty cycle must stay at 10% despite what sample frequency is adjusted to. Looked a quite a few designs but everytime my frequency changes the duty cycle changes aswell. Was thinking about generating a pulse train with fixed duty cycle and multiplying it by the anlog input signal?
Any advice or ideas would be very helpful.
Thanks,
Josh
