Modulation schemes can be analog or digital. An analog scheme has an input wave that varies continuously like a sine wave. In digital modulation scheme, voice is sampled at some rate and then compressed and turned into a bit stream, and this in turn is created into a particular kind of wa...
1.Definition of Modulation: Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. 2.Understanding Carrier Signal: A carrier signal is characterized by a steady waveform, which means it maintains a constant height (amplitude) ...
Analog Modulation The most common use for analog modulation is transmitting radio signals over long distances. It used to be the primary method for sending other signals like television and voice communication, but those signals now use digital modulation instead. ...
Modulation is primarily used in telecommunication technologies that require the transmission of data via electrical signals. It is considered the backbone of data communication because it enables the use of electrical and optical signals as information carriers. Modulation is achieved by altering the perio...
Step-by-Step Solution:Step 1: Definition of Modulation Modulation is the process of varying one or more properties of a carrier wave in accordance with the information signal that is to be transmitted. In commu

A type of signal modulation that is used to encode the message information in the amplitude of a sequence of signal pulses is termedpulse amplitude modulation. Modulationis the act of changing one or more features of a periodic waveform, called the carrier signal, with a second signal, called...
In subject area:Computer Science A modulation scheme is defined as the method used to convert information bits into physical symbols in communication systems. It can be adapted to the channel conditions to balance communication rate and reliability, with denser constellations leading to higher rates bu...
