Communication Systems
Types of Communication
Modulation
100

Collection of electronic components and circuits that converts the electrical signal into a signal suitable for transmission over a given medium

Transmitter

100

The simplest method

simplex

100

makes the information signal more compatible with the medium

modulation

200

Medium by which the electronic signal is sent from one place to another

Communication Channel

200

The form of two-way communication in which only one party transmits at a time

Half Duplex communication

200

the baseband information signal called the modulating signal varies the amplitude of the higher-frequency carrier signal

Amplitude modulation

300

Collection of electronic components and circuits that accepts the transmitted message from the channel and converts it back into a form understandable by humans

Receivers

300

The telephone is an example of this type of communication.

full duplex communication

300

the information signal varies the frequency of the carrier.
