Hi hut_dt6_k50

Wellcome to the forum

Digital and analog are two basic terms used in Electronics Engineering for justification the signal type coming into device or going from device. Digital signal has only two conditions 0 or 1. For example, you push the switch on of a bulb and it illuminates and if you push the switch off, the bulb is also off. It means you have only two conditions, 0 (when switch is off) and 1(when switch is on).
Analog signal is the signal which changes its value between given two limits. For example, the fan dimmer is an analog device with which you control the speed of a fan for a desired limit.
These two type of signals use for designing the electronic PCBs by using ICs.
Hope this will help you.
