This signal can be defined by bit interval as well as bit rate. Every digital signal has amplitude, frequency, & phase like the analog signal. These signals can be decomposed into sine waves which are termed as harmonics. A digital signal carries the data in the form of binary because it signifies in the bits. These signals are discrete or not continuous. Similar to analog, digital signals carry the data although it is a bit different. The analog signal value range cannot be fixed. An analog signal is not resistant toward the noise, therefore it faces distortion as well as reduces the transmission quality.

Amplitude streaks the highest height of the signal, frequency streaks the rate at which an analog signal is varying, and phase streaks the signal position with respect to time nothing. An analog signal can be defined by using amplitude, time period otherwise frequency, & phase. A simple type of analog signal is nothing but a sine wave, and that can’t be decomposed, whereas a composite type analog signal can be decomposed into numerous sine waves. Please refer the link to know about Difference Between Analog Circuit and Digital CircuitĪn analog signal is one type of continuous time-varying signals, and these are classified into composite and simple signals. This article discusses an overview of both analog as well as digital signals, and comparison between them. As some of the other languages can only recognize as well as speak one of the two. These two kinds of signals are similar to different electronic languages. In some way, an electronics project mainly interacts by the real analog world whereas digital signals with computers, microprocessors, and logic units. The best example of an analog and digital is electrons because it deals with analog as well as digital signals, input & outputs. Let us discuss some dissimilarity of analog & digital signals. The main difference between analog and digital signals is, analog signals are represented with the sine waves whereas digital signals are represented with square waves. Analog signals are continuous wave signals that change with time period whereas digital is a discrete signal is a nature. Analog and digital signals are different types which are mainly used to carry the data from one apparatus to another.
