A technique by which analog signal gets converted into digital form in order to have signal transmission through a digital network is known as Pulse Code Modulation. It is abbreviated as PCM. It is basically signal coders also known as waveform coders.

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

Aug 24, 2023 · Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. Learn its block diagram, steps, types, advantages, and applications. English

Pulse code modulations are of two types: Differential pulse code modulation (DPCM) Adaptive differential pulse code modulation (ADPCM) Differential pulse-code modulation is a signal encoding process which adds functionalities based on the prediction of the samples of the signal.

Pulse code modulation is a method that is used to convert an analog signal into a digital signal so that a modified analog signal can be transmitted through the digital communication network. PCM is in binary form, so there will be only two possible states high and low(0 and 1).

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.

Mar 17, 2025 · Here, we will discuss the PCM (Pulse Code Modulation) technique, one of the digital modulation methods to transmit the signal. A PCM system converts an analog input signal to the digital signal , which is a combination of the binary sequence created from the …

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.

Figure 18.19 shows a basic block diagram of a Pulse Code Modulation speech terminal. When transmitting, the audio signal is first band limited to minimise aliasing or foldover distortion and then sampled to form a PAM signal.
