- FUNCTION DESCRIPTION
-
- 20, 36, 44, 52, 64, 72, 88 bits algebraic codebook decoder.
- 4 tracks x 16 positions per track = 64 samples.
-
- 20 bits --> 4 pulses in a frame of 64 samples.
- 36 bits --> 8 pulses in a frame of 64 samples.
- 44 bits --> 10 pulses in a frame of 64 samples.
- 52 bits --> 12 pulses in a frame of 64 samples.
- 64 bits --> 16 pulses in a frame of 64 samples.
- 72 bits --> 18 pulses in a frame of 64 samples.
- 88 bits --> 24 pulses in a frame of 64 samples.
-
- All pulses can have two (2) possible amplitudes: +1 or -1.
- Each pulse can have sixteen (16) possible positions.
