Notch width and depth
The width of the notch filter is the ratio of the width of –3 dB attenuation frequency band with respect to
the notch frequency at its center when depth is 0, and the value is as shown in the table below.
The notch filter depth indicates I/O ratio where the input at the center frequency is completely shut with
setup value 0 but fully received with setup value 100. The table below shows this value in dB on the right.
