Combined digital and analog filter characteristics.
The passband and stopband edges scale with frequency. For input sample rates, Fs, other than
48 kHz, the 0.05 dB passband edge is 0.4535×Fs and the stopband edge is 0.5465×Fs.
Digital filter characteristics.
Measurement Bandwidth is 10 Hz to Fs (kHz)
