Embedded systems are specialized computing systems designed to perform specific tasks within larger systems. These systems are found in various industries, each tailored to meet specific requirements. The types of embedded systems include real-time embedded systems, networked embedded systems, mobile embedded systems, standalone embedded systems, and more. Real-time embedded systems are crucial in applications that

Analog Communication Analog communication refers to the transmission of data through continuous signals, where the signal varies in a smooth and continuous manner. This method predates digital communication and is still in use today for various applications. In analog communication, the original signal is directly transmitted without any conversion to binary code, unlike digital communication

The amplitude of the carrier signal is

WHY MODULATION? (i) Long distance communication The purpose of a modulation is to convert the message signal into a suitable form that matches to the transmission medium. This is necessary because the message signal is a low frequency signal that cannot be transmitted effectively over the transmission channel directly. These channels are best suited for high

Communication is the process of establishing connection or link whereby the information is transferred from one point called as source to the other point called as destination. Two of the main barriers in communication are the language and the distance.  Out of them, the distance problem is solved now-a-day by means of long distance communication.

A general communication system involves the transmission of information between two or more entities using a shared medium or channel. It typically consists of a sender that encodes a message, a transmission medium through which the message travels, a receiver that decodes the message, and a feedback mechanism to ensure accurate communication. The effectiveness of
