This amounts to PCM ( pulse code modulation ) with digitization performed by a sigma-delta ADC.
2.
The lowpass signals are then quantized and encoded using special techniques like, Pulse Code Modulation ( PCM ).
3.
It uses sub-band adaptive differential pulse code modulation ( SB-ADPCM ) within a bit rate of 64 kbit / s.
4.
He also worked on pulse code modulation and wrote a book on " Modulation Theory " ( Van Nostrand, 1953 ).
5.
In this system permutation matrices were used to scramble coded representations ( such as Pulse Code Modulation and variants ) of the speech data.
6.
It's 159 pages of fine print, and not a dull page in the lot, if you like reading about refraction indexes and pulse code modulation.
7.
It also has applications in pulse code modulation as a pulse shape for transmitting digital signals and as a matched filter for receiving the signals.
8.
The station also uses a BBC-designed pulse code modulation digitisation technique similar to NICAM, which is used for outside broadcasts running through a telephone line.
9.
A single-bit error in audio data stored directly as linear pulse code modulation ( such as on a CD-ROM ) causes, at worst, a single click.
10.
The Gray code is sometimes attributed, incorrectly, to Elisha Gray ( in " Principles of Pulse Code Modulation ", K . W . Cattermole, for example ).
