Question

What is the difference between analog signal and digital signal?

Answer 1

Hint: Analog signals are continuous types of signals while digital signals are discrete types of signals. Analog signals and digital signals are mainly used to carry the data from one apparatus to another apparatus.

Complete step-by-step answer:
The main difference between analog signals and digital signals is that analog signals are represented with sinusoidal waveforms and digital signals are represented with square waveforms.
Adaptability-Analog signals are less adjustable for a range of use, whereas digital signals are more adjustable for a range of use.
Continuity- Analog signals use a continuous variety of amplitude values whereas digital signal takes a limited set of distinct values at consistently spaced spots in the time.
Type of Data- Analog signals are continuous in nature, whereas digital signals are discrete.
Type of Waves- Analog signal wave type is sinusoidal, whereas a digital signal is a square wave.
Medium of Transmission -Analog signal medium of transmission is wire or wireless, whereas a digital signal is a wire.
Type of Values- Analog signal value type if positive as well as negative, whereas a digital signal is positive.
Security- The security of an analog signal is not encrypted, whereas a digital signal is encrypted.
Bandwidth-The analog signal bandwidth is low, whereas the digital signal is high.
Hardware- Analog signal hardware is not elastic, whereas digital is elastic in execution

Note: The data storage of an analog signal is in the wave signal form, whereas digital signal stores the data in the binary bit form. Analog signals are portable similar to the thermometer and low cost, whereas digital signals are portable similar to computers and expensive. In analog, the signal can be deteriorated due to noise throughout transmission, whereas digital signals can be noise resistant throughout transmission devoid of any deterioration.
