The designator and the weapon must be set to the same pulse code
, the delivery system must place the weapon into the required footprint or envelope and the designator must 'lase' at the correct time and for the required duration.
Electrical engineer Reeves invented Pulse Code
Modulation and so established the basis of modern digital communication.
The voltage or signal level is then converted to a numeric value using a scheme called pulse code
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.
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 2.32 Mbit/s in both directions (symmetrical) over one copper line.
The original purpose of a Gray code was to avoid errors in signals transmitted by pulse code
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.
V.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.
The tactical multichannel radio and cable systems that the Signal Corps developed featured pulse code
modulation; the only tactical telephone switchboards used were manual.
