Hello,
I've a bandpass filter centered at 40kHz. The filter is working nice when I send it a sinusoid/square wave/triangle wave, but when it receives the actual signal that I need it to filter which is a sawtooth wave the filter converts it to a triangular wave (which is part of the reason I'm using a filter) but it cuts the frequency by half. In turn, my transmitter filters the 20kHz signal. Does someone know how to modify the bandpass filter to receive a 40kHz output?
Thank you.
