pulse code modulation

Most widely used techniques for digitizing information signals for electronic data transmission

The available range of signal voltages is divided into levels, and each is assigned with a binary number.

Ratio of the strongest possible signal that can be transmitted and the weakest discernable signal.

Needed to ensure that the transmitter and receiver agree on which bits constitute one sample.

Involves using a compressor amplifier at the input, with greater gain for low-level than for high-level signals.

Reduces the quantizing error for small signals
