The High Pass Filter Circuit. In this circuit arrangement, the reactance of the capacitor is very high at low frequencies so the capacitor acts like an open circuit and blocks any input signals at VIN until the cut-off frequency point ( ƒC ) is reached. Above this cut-off frequency point the reactance of the capacitor has reduced sufficiently as to now act more like a short circuit allowing all of …

butter_high-pass_filter uses signal.filtfilt; the input to the function is in short format (bug 1) data_chunk=array('h',data) data_chunk = butter_high-pass_filter(data_chunk,10000,RATE) data_chunk is never used, so a high passed frame of audio is never saved to file (bug 2) data is read for 5 seconds worth audio

Since the formula for a high-pass RL filter is f= R/2πL, doing the math we get, f= R/2πL= 10KΩ/ (2 (3.14) (470mH))= 3,388 Hz, which is approximately 3.39KHz. This means all frequencies above 3.39KHz will be passed through without attentuation, while frequencies below this value will begin to get attenuated.
