Hi all,
Currently, I have a microcontroller that puts out a 1000Hz signal but the low-pass filter I have built only converts PWM to analog for a PWM carrier frequency of about 10kHz. Is it possible to adjust the PWM frequency that will work for the filter? I'm using a 3rd order, op-amp LPF, shown in this link..
