Looking for what is Quantization and its types? In this article, we explained all the important points regarding quantization in detail. let’s understand the topic: Quantization is a process of converting discrete time continuous valued signal (discrete time signal) into discrete time discrete valued signal (digital signal). Other definition of quantization, It is the process of … Read more
Looking for delta modulation (DM or ∆-modulation)? In this article we explained all main and important points regarding Delta Modulation (DM) in detail. let’s understand the topic: like PCM (Pulse Code Modulation) and DPCM (Differential Pulse Code Modulation), Delta modulation (DM or Δ-modulation) is also a analog-to-digital modulation technique used for converting analog signals into … Read more
Looking for Differential Pulse Code Modulation (DPCM)? In this article we explained all main and important points regarding Differential Pulse Code Modulation (DPCM) in detail. let’s understand the topic: In PCM (Pulse code modulation) It is observed that, the adjacent samples of a signal are highly correlated with each other. So, the adjacent sampled valued … Read more
Pulse code modulation (PCM) is a digital modulation technique by which analog signal gets converted into digital form for transmission, storage, or processing. It involves sampling, quantizing, encoding, and, if needed, reconstructing the original analog signal. Basics of Pulse Code Modulation (PCM) Pulse Code Modulation (PCM) is a digital scheme, that digitize all forms of analog … Read more
The sampling theorem, also known as the Nyquist-Shannon sampling theorem, is a fundamental concept in signal processing and digital communication. Sampling is a process of converting a continuous-time analog signal into discrete-time signal. This conversion is done with the help of sampler. Sampling is the second step in Pulse Code Modulation (PCM) technique where we … Read more
A block diagram of digital communication system represents the various functional elements and stages involved in transmitting and receiving digital data. Block Diagram of digital communication system having three sections Block diagram of Digital Communication System Digital Communication-Overview Read More 1.Transmitter Section It include various functional elements such as Information Source, Input Transducer, Source Encoder, … Read more
Communication is a process of transmitting information or exchange of information from one point to another. The exchange of information in our daily life is in the form of signals. These real life signals, like audio signals are, generally analog in nature. So, if we want to establishes communication over a long distance, then the analog … Read more
