High Pass Filter Audio Circuit. The above circuit is an rl high pass filter. Since the cutoff is strictly determined by r and c choose the appropriate resistor and capacitor to cutoff frequencies where you want to.
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 the input signal to pass directly to the output as shown below in the filters response curve. Audio filter circuit can be formed by simple cascading high pass filter circuit and low pass filter circuit and is generally the choice for simplicity of design and performance through such a circuit can be realized by number of possible circuit. High pass filter an active first order high pass filter is connected in the circuit.
Input capacitor output resistor ground.
