PWM signal to Audio signal possible?

[thx_dts71]

hello everybody,

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.
pls help..
thanks!

Absolutely! The simplest one is for example a 3k3 resistor from the PWM output to the input of amplifier and a 1n5 capacitor in parallel with the input of the amp.
