Note 12 : These frequencies scale with the sampling frequency(fs).
Note 13 : Stopband is 26.5kHz to 3.0455MHz at fs=48kHz.
Note 14 : Passband is DC to 21.5kHz at fs=48kHz.
Note 15 : The analog modulator samples the input at 3.072MHz for a system sampling rate of
Note 16 : The calculation delay time occurred by digital filtering. This is the time from the input of
