What is Band Stop RC Filter?

The band stop or notch filter is another filter design with two corner or cut-off frequencies. The band stop filter blocks (rejects) or severely attenuates a certain band of frequencies between its two corner frequencies while allowing all those outside of this stop-band to pass. A second-order RC band stop filter is constructed as follows:BAND STOP RC FILTER

The frequency at which maximum stop attenuation occurs is given as:

`f_{STOP}=\frac{1}{2\piRC}`
