Notch Filter Width and Depth
Width Setting
This is the ratio of the frequency bandwidth at a damping factor of -3 [dB] relative to the center
frequency when the depth is 0. This value should conform to the left column in the table below.
Depth Setting
This is the I/O ratio at which the center frequency input is completely cut off at a set value of 0
and completely passed at a set value of 100. If the indication unit is [dB], this value should
conform to the right column in the table below.
