analog delay vs digital delay

This page on analog delay vs digital delay describes difference between analog delay and digital delay. As the name delay suggests that it refers to delaying signals in time depending upon the application.We will see the terms with respect to electronics/communication.


Analog delay

Analog delay is the delay of the analog signal as it travel through the electronic components/circuits and/or propagation medium.


Digital delay

Digital delay is the delay of the digital signals(binary pulses 1s and 0s) as it travel through the logic gates(AND,OR,FLIPFLOPs,Latch etc.) Various techniques are developed for delay equalization as well as delay compensation as per the need for various digital form of modulation/communication.

As far as music application is concerned, analog delay takes the sound as input and without much of the delay just play the same back. While digital delay,takes the music/sound, converts it to the digital form,and play-back after some amount of the delay. Analog delay usually is in milli-seconds while digital delay can go upto seconds.
