`
`Analog and Digital are the different forms of signals. Signals are used to carry
`information from one device to another. Analog signal is a continuous wave that
`keeps on changing over a time period. Digital signal is discrete in nature. The
`fundamental difference between analog and digital signal is that analog signal is
`represented by the sine waves whereas, the digital signal is represented by
`square waves. Lets us learn some moredifferences between analog and digital
`signal with the help of comparison chart shown below.

`
`Definition of Analog Signal
`
`Analog signal is a kind of continuous wave form that changes over time. An
`anlaog signal is further classified into simple and composite signals. A simple
`analog signal is a sine wave that cannot be decomposed further. On the other
`hand, a composite analog signal can be further decomposedinto multiple sine
`waves. An analog signal is described using amplitude, period or frequency and
`phase. Amplitude marks the maximum height of the signal. Frequency marks the

`
`An analog signal is not immune to noise hence, it faces distortion and decrease
`the quality of transmission. The range of value in an analog signal is not fixed.
`
`Definition of Digital Signal
`
`Digital signals also carry information like analog signals but is somewhatis
`different from analog signals. Digital signal is noncontinuous, discrete time signal.
`Digital signal carries information or data in the binary form i.e. a digital signal
`represent information in the form of bits. Digital signal can be further
`decomposedinto simple sine waves that are called harmonics. Each simple wave
`has different amplitude, frequency and phase. Digital signal is described with bit
`rate and bit interval. Bit interval describes the time require for sending a single
`bit. On the other hand, bit rate describes the frequency of bit interval.

`
`A digital signal is more immune to the noise; hence, it hardly faces any distortion.
`Digital signals are easier to transmit and are more reliable when compared to
`analog signals. Digital signal has a finite range of values. The range of a digital
`signal liesbetween 0 to 1.
`
`Key Differences Between Analog and Digital Signal
`
`1. An analog signal represents a continuous wave that keeps changing
`over a time period. On the other hand, a digital signal represents a
`noncontinuous wavethat carries information in a binary format and
`has discrete values.
`
`. An analog signal is always represented by the continuous sine wave
`whereas, a digital signal is represented by square waves.
`
`. While talking of analog signal we describe the behaviour of the wave
`in respect of amplitude, period or frequency, and phase of the wave.
`On the other hand, while talking of discrete signals we describe the
`behaviour of the wavein respect of bit rate and bit interval.
`
`. The range of an anlaog signal is not fixed whereas the range of the
`digital signal is finite and ranges between 0 to 1.
`
`. An analog signal is more prone to distortion in response to noise, but
`a digital signal has immunity in response to noise henceit rarely
`faces any distortion.
`
`. An analog signal transmits data in the form of wave whereas,a digital
`signal transmits the data in the binary form i.e. in the form ofbits.
`
`. The best example of an analog signal is a human voice, and the best
`example of a digital signal is the transmission of data in a computer.
`
`Conclusion:
`
`Digital signal is nowadays replacing the analog signal, but analog signal is still
`best for audio transmission.
