Companding is usedGroup of answer choicesin PCM receivers, to overcome impulse noiseto protect small signals in PCM from quantizing distortionto protect small signals in PCM from quantizing distortionin PCM transmitters, to allow amplitude limited in the receiversto overcome quantizing noise in PCM

With digital companding, the analog signal is first sampled and converted to a linear PCM code and then the linear code is digitally compressed.Group of answer choicesTrueFalse

Which of the following is not a benefit of companding?Group of answer choicesMinimizes number of bitsMinimizes signal bandwidthMinimizes quantizing errorMinimizes noise

Historically, digital compression was implemented using specially designed diodes inserted in the analog signal path in a PCM transmitter prior to the sample-and-hold circuit.Group of answer choicesTrueFalse

In the receiver, the compressed PCM code is expanded and then decoded (converted back to digital).Group of answer choicesTrueFalse
