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.

In this article, let us study in detail about one of the digital modulation techniques, Pulse code modulation (PCM). 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.

Pulse-code modulation (PCM) is a method used to digitally represent analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications.

Pulse Code Modulation in Digital Communication - Learn about Pulse Code Modulation (PCM) in Digital Communication, including its principles, applications, and advantages.

Block Diagram of Pulse Code Modulation. Here is a block diagram of the steps which are included in PCM. In sampling, we are using a PAM sampler that is Pulse Amplitude Modulation Sampler which converts continuous amplitude signal into Discrete-time- continuous signal (PAM pulses). The basic block diagram of PCM is given below for better ...

Jul 12, 2018 · Pulse code modulation (PCM) and demodulation circuit diagrams are essential components of any digital system or device. Propagated in the form of electrical pulses, PCM is a method of encoding analog data into a digital representation.

Apr 1, 2025 · Pulse Code Modulation (PCM) is a digital modulation technique where the analog signal is coded into digital pulses. Here, we will see the block diagram of the PCM system or Pulse Code Modulation system to understand its working principle.

PCM (Pulse Coded Modulation) is a waveform-coding scheme designed to reproduce the waveform output of the source at the destination with minimum distortion.

PCM -> analog-to-digital (ADC) conversion. Instantaneous samples of an analog signal are represented by digital words in a serial bit stream. 3 main steps: Sampling (i.e., flat-top PAM), Quantizing (fixed number of levels is allowed), and Encoding (binary digital word). Analog signal x(t) is bandlimited to F . If not, LPF is used.
