An analog communication system is a communication system where the information signal sent from point A to point B can only be described as an analog signal. An example of this is Monica speaking to Carl over the telephone, as described in Section 1.2.2 .
8 Μαΐ 2024 · Communications: Analog signals are used in telephone and radio communications. In telephone systems, analog signals are used to transmit voice signals over long distances. In radio communications, analog signals are used to transmit audio and video signals.
Analog transmission is a transmission method of conveying information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that information.
An electrical impulse or an electromagnetic wave which travels a distance to convey a message, can be termed as a signal in communication systems. Depending on their characteristics, signals are mainly classified into two types: Analog and Digital. Analog and Digital signals are further classified, as shown in the following figure. Analog Signal
Analog format refers to the representation of signals in a format such as YC1C2 used in analog and digital TV, where Y denotes signal luminance, allowing compatibility with monochrome displays and potential bandwidth reduction on chrominance signals without compromising perceptual quality.
We study two broad classes of techniques: amplitude modulation, in which the analog message signal appears directly in the I and/or Q components; and angle modulation, in which the analog message signal appears directly in the phase or in the instantaneous frequency (i.e., in the derivative of the phase) of the transmitted signal.
