PWM signal to Audio signal possible?
can u help me convert PWM signal from this HT processor to
produce audio signal.
here's the block diagram of PS9818
what i'm gonna do is, to extract the audio signal from the PWM modulator.i dont intend to use the 6ch switching power stage.
i already have a DIY-mosfet 6ch amp.
here's the processor:
note that PWM 1 to 8.thats the output stage going to the 6ch switching power stage that i omitted.
some say, i should use LPF (low pass filter) to decode this signal.
is it possible?is anybody here have a LPF design suitable for this application.
do it look like this?
