Analog:
Signal Shape: Smooth and continuous
Numerical Values for Signal Estimations: Analog signals speak to one ceaseless variable as the result of another ceaseless time-based variable.
Amount of Information that can be transmitted: analog circuits can conduct as it were reasonably low-speed information communications.
Energy necessities: light, sound, temperature, position, and pressure Privacy and security : not encrypted
Clarity of Signal: clamor influences clarity and quality, commotion is amplified,
Digital:
Signal shape: stepping, square, and discrete
Numerical Values for Signal Measurements: digital communication methods transmit a complete measured value, in other words both a numeric value and a unit of measurement
Amount of data that can be transmitted: First of all, it is theoretically possible to transmit digital signals directly.
Energy requirements: voltage, accoustic pressure.
Privacy and security: encrypted
Clarity of signal: noise is lower in amplitude, electronics can ignore the noise, quality of signal is maintained, signal is high
Analog and digital is :
Analog signal could be a continuous signal which speaks to physical estimations.
Digital signals are discrete time signals created by computerized balance.
Example :Human voice in discuss, analog electronic gadgets. Computers, CDs, DVDs, and other advanced electronic gadgets.
