A signal is pulse code modulated to convert its analog information into a binary sequence, i.e., 1s and 0s. The output of a PCM will resemble a binary sequence. The following figure shows an example of PCM output with respect to instantaneous values of a given sine wave.
Block diagram of the Pulse Code Modulation process is as shown in the figure below. In the PCM process, it is possible to digitise all forms of analog data, including music, telemetry, voice, full-motion video.
The block diagram of the Pulse Code Modulation system is shown below: The components of a PCM system are a low pass filter, sampler, quantizer, encoder, communication channel, quantizer, decoder, and a reconstruction filter .
Apr 15, 2016 · 1. PCM Transmitter. Fig.2 shows a practical block diagram of a PCM generator or transmitter. Fig.2 : PCM Transmitter. In PCM transmitter , the signal x(t) is first passed through the low-pass filter of cut-off frequency f m Hz .
The Pulse Code Modulation process is done in three steps Sampling, Quantization, and Coding. There are two specific types of pulse code modulations such as differential pulse code modulation (DPCM) and adaptive differential pulse code modulation (ADPCM).
Block diagram of Pulse Code Modulation. The figure below shows the block diagram representing a PCM system. It is basically composed of a transmitter, a transmission path and a receiver. The transmitter performs the sampling, quantizing and encoding of the signal.

May 17, 2024 · The block diagram of a PCM system is shown in Fig. 18.17. The modulating signal m(t) is applied to the input of the volume compressor unit. A sampling circuit generates a PAM signal from the compressed signals, which is then multiplexed with signals from other input channels.
1 Citations. Abstract. Pulse Code Modulation (PCM), also known as baseband transmission, converts the input analog signal into digital format and transmits over a digital communication channel. It involves: Band limiting the input analog signal. Sampling. Quantization. A to D conversion. Signal shaping.
