5.19.1
Voice coding function includes a 50 kHz second-order, low-pass anti-aliasing filter, an analog-to-digital converter, digital filters
for decimation, band-passing, frequency ripple compensation, and DSP interface logic. The audio input A/D converter converts
the incoming signal to 13-bit two’s-compliment linear PCM words at an 8 or 8.1 kHz rate. Following the A/D converter, the
signal is digitally filtered, low-pass, and selectable high-pass.
