Meet The Author

I have great pleasure to present this book on Communication Electronics, S.Y.B.Sc. Electronic Science, of B.Sc (Computer Science). Paper-I, Semester-III, EL-231, CBCS (June-2020-21).

It is written as per the 2020-21 pattern of Choice Base Credit System (CBCS) syllabus of Savitribai Phule Pune University,Pune-411007 implemented from June-2020.

The Author and Co-Author have taken efforts and tried there level best to simplify the difficult concept in Communication Electronic with neat diagram and simple mathematical equation.

The basics of Communication Electronic which requires to understand the concept of various types of Communication such as Base Band Communication, Broad Band Communication, Concept of Noise, signal-to-noise (S/N) ratio, Noise figure and noise temperature Need of modulation and Demodulation.

Continuous-wave modulation techniques: Amplitude, Frequency and Phase Modulation, Definition, Modulation Index, AM Receiver: Demodulater circuit using diode and super-hetero dyne receiver, characteristics of receiver: selectivity, sensitivity. FM Modulation using Varactor diode. FM Demodulater: Foster-Seeley detector. Block Diagram of FM communication system.

Concept of PAM, PWM, PPM, Time Division Multiplexing and Frequency Division Multiplexing. Block diagram of digital communication system, bit rate, baud rate and bandwidth. Serial and parallel communication, concept of sampling, Sampling theorem, PCM concept of keying techniques: ASK, FSK, PSK Block diagram of MODEM.
