(a) which algorithm is used to digitize a voice signal for transmission in a digital circuit-switched network? (b) at which data rate is the voice signal transmitted?

Answers

Answer 1

Pulse code modulation (PCM) algorithm is used to digitize a voice signal for transmission in a digital circuit-switched network

An average voice channel in a circuit switched digital telecommunications network uses a 64 kbit/s timeslot. For the purpose of digital transmission, an analogue voice signal is transformed using the pulse code modulation (PCM) technique.

In order to represent sampled analogue signals digitally, one technique is pulse-code modulation (PCM). It serves as the industry standard for digital audio in applications such as digital telephony, compact discs, and computers.

Sampling, quantization, and coding are the three processes in the Pulse Code Modulation process.

The telephone network (POTS) uses PCM (Pulse Code Modulation), a standardised technique, to convert an analogue signal to a digital one. First, an 8-kHz sampling rate is used to sample the analogue signal.
