Unit 3 Basics Of Modulation Technique1 Pdf Modulation is the process of varying one or more properties of a high frequency periodic waveform, called the carrier signal, with a modulating signal which typically contains information to be transmitted. One method to produce signal sideband (ssb) amplitude modulation is to produce dsbam, and pass the dsbam signal through a band pass filter, usually called a single sideband filter, which passes one of the sidebands as illustrated in the diagram below.

The document discusses modulation, explaining its definition as the operation of varying the carrier signal’s amplitude, frequency, or phase in accordance with a message signal. This document discusses analog communication systems and amplitude modulation. it defines three main types of modulation: amplitude, frequency, and phase modulation. The qam modulation scheme encodes data by varying both amplitude and phase of the carrier signal. thus, it is sometimes viewed as a combination of ask and pskmodulation. Introduction amplitude modulation is the simplest and earliest form of transmitters am applications include broadcasting in medium and high frequency applications, cb radio, and aircraft communications basic amplitude modulation the information signal varies the instantaneous amplitude of the carrier am characteristics am is a nonlinear.
