1.What is Electronic?

The study and use of electrical devices that operate by controlling the flow of electrons or other electrically charged particles.

2.What is communication?

Communication means transferring a signal from the transmitter which passes through a medium then the output is obtained at the receiver. (or)communication says as transferring of message from one place to another place called communication.

3.Different types of communications? Explain.

Analog and digital communication.
As a technology,analog is the process of taking an audio or video signal (the human voice) and translating it into electronic pulses. Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of "1"s and "0"s.
Digital signals are immune to noise,quality of transmission and reception is good,components used in digital communication can be produced with high precision and power consumption is also very less when compared with analog signals.

4.What is sampling?

The process of obtaining a set of samples from a continuous function of time x(t) is referred to as sampling.

5.State sampling theorem.

It states that,while taking the samples of a continuous signal,it has to be taken care that the sampling rate is equal to or greater than twice the cut off frequency and the minimum sampling rate is known as the Nyquist rate.
