It is an audio codec standardized by an International Telecommunication Union, which uses the Sub-band Adaptive Differential Pulse Code Modulation with the bitrate of 64 kbps.
PCM: Pulse code modulation, a form of data transmission in which amplitude samples of an analog signal are represented by digital numbers.
Designed to be compatible with all laser-guided weapons conforming to the Nato Stanag No 3733 standard, it can be programmed to handle Russian or other patterns of pulse code.
Pulse code modulation provides only an approximation of the original analog signal, as shown in Figure 4.
Other features include its Dynamic Acoustics technology, which allows the piano to replicate the direct sounds of hammers striking string, delivering the reflective and resonating sounds of an acoustic piano performance, and its Pulse Code Modulation, which includes settings for grand, upright and electric piano and also features the tones of a harpsichord, pipe organ and strings.
The new IMA devices are the only IMA chips that support both Universal Test & Operations Physical Interface for ATM (UTOPIA) Level 2 and serial pulse code modulated (PCM) physical layer interfaces, making the chip ideal for either T1/E1 applications where PCM is the most popular interface or DSL applications where UTOPIA 2 is favored.
The original purpose of a Gray code was to avoid errors in signals transmitted by pulse code modulation.
As such, the device is based on standard pulse code amplitude modulation (PAM) 16 line code and supports transmission rates of 192 kbit/s to 2.
Later experiments used a hybrid system involving Beta and Video Home System (VHS) format video tapes on which Pulse Code Modulation (PCM) files were recorded.
92 also includes a capability called pulse code modulation (PCM) upstream, which boosts the upstream data rates from the user to the ISP to reduce transfer times for large files and email attachments sent by the user.
ISDN is based on the development of pulse code modulation (PCM), which samples existing analog signals at a rate of 64 kbps.
