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.
The basic operations in the receiver section are regeneration of impaired signals, decoding, and reconstruction of the quantized pulse train. Following is the block diagram of PCM which represents the basic elements of both the transmitter and the receiver sections.
When a digital signal undergoes Pulse Code Modulation, it converts the analog information into a binary sequence (1 and 0). Through the demodulation process, we can obtain the original analog signal. The figure below represents the output of the PCM signal with respect to the sine wave.
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).
Such as, the method of transmission is performed using the PCM system. 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.
The PCM system block diagram illustrates the various components involved in the process of converting analog signals into digital data. The key components in a PCM system block diagram include: Transducer: Converts physical quantities into electrical signals.

Pulse Code Modulation System. 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.
