6. Filter characteristics scale with output sample rate.
7. The analog modulator samples the input at 6.144 MHz for an output sample rate of 48 kHz. There is no
rejection of input signals which are multiples of the sampling frequency (n x 6.144 MHz ±21.7 kHz where
n = 0,1,2,3…).
8. Group delay for Fs = 48 kHz, tgd = 15/48 kHz = 312µs.
