Peak filters
The first step is the calculation of the constant gain obtained from the gain filter parameter
(GdB is expressed in dB).
Equation 18
The filter coefficients are different if the gain is positive or negative.
4.2.1
Peak filter - negative gain (cut)
The cut value is calculated with the following equation:
Equation 19
The filter coefficient can be calculated as follows:
