High Pass Filter : Circuit, Characteristics and Its Applications
The capacitor produces the required amount of reactance or high reactance to attenuate the low frequencies of a signal, i.e., below the cut-off frequency. At low reactance of the capacitor, the RC high pass filter allows the high-frequency components of a signal i.e., greater than the cut-off frequency.
