Braking systems in vehicles play a critical role in ensuring safety and control during driving. The integrated braking system is a sophisticated technology that combines various components to enhance braking efficiency. These...
An AM wave expression consists of carrier and two sidebands. The carrier component of the modulated wave has the same amplitude as the unmodulated carrier. The AM modulated wave contains extra power in the two sideband...
Mathematical or Time Domain Representation of an AM Equ-1 Modulating signal Equ-2 Carrier signal Where, – Amplitude of the carrier signal (volts), and – Amplitude of the modulating signal (volts). The amplitude of...
The modulation process is required in a communication system to achieve the following basic needs Ease of radiation, Adjustment of bandwidth, Reduction in height of antenna, Avoids mixing of signals, Increases the range of...
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...
Generally signals are single valued functions of time that convey the information which may be real (or) complex valued. The main classifications of signals are as follows. (i) Continuous – Time (CT) signals The signals...
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...
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 two basic types of communications systems are: Analog communication systems, and Digital communication systems. An analog communication is a system in which the information signal is transmitted and received in an analog...
