What Is Multi-frequency Filter?

- Sep 28, 2018-

The multi-frequency filter is also called a multi-frequency compensator, which is actually a combination of several single-frequency filters. The full frequency domain of the signal is divided into several segments, and the LC circuit is used to control the gain from the ground to achieve the change of the amplitude of the center frequency of each segment, which constitutes an ideal frequency response curve. In general, the mid-band is constructed in the form of a single-frequency or multi-frequency filter.
