### Cut -off frequency

1. The equation to find the cut-off frequency for a circuit with two multiple poles (at the same frequency the two poles).

2. The cut-off frequency for a circuit with two closed poles Wp1 and Wp2 and two closed zeros Wz1 and Wz2.

### Re: Cut -off frequency

A cutoff frequency, corner frequency, or break frequency is a boundary in a system's frequency response at which energy flowing through the system begins to be reduced (attenuated or reflected) rather than passing through.
