WebThe corner frequencies for RC filter and RL filter are as follows: For RC filters: (1) For RL filters: (2) Frequency Response: It is a graph of magnitude of the output voltage of the filter as a function of the frequency. It is generally used to characterize the range of frequencies in which the filter is designed to operate within. Webthe input signal, while high-pass fllters serve to difierentiate the input signal. Furthermore the range over which each type of circuit was determined empirically, giving a working range of approximately 1:2§ 0:1 kHz and higher for the low pass fllter as an integrator and 50¡600 Hz for the high-pass fllter as a difierentiator.
