Hi all ,
I have this question i'm pritty annoyed with.
Would it be possible to controll the capacitance of a capacitor with PWM.
I would use somthing like the picture below.

V1 would be the audio and V2 would be the PWM signal.
I'm asking because i'd like to make a speaker simulator. So i can recreate all sorts of impedance curves to test amplifiers without actualy owning the speakers.
ty for ur help.
