5. Filter characteristics scale with output sample rate.
6. The analog modulator samples the input at 128 times Fs. For example, to obtain an output sample rate
7. High Pass Filter characteristics are specified for Fs=44.1 kHz.
of 48 kHz the input must be sampled at 6.144 MHz. There is no rejection of input signals which are
multiples of the sampling frequency (n × 6.144 MHz ±20.0 kHz where n = 0,1,2,3...).
