EC107 Analog Communication

1. Introduction to the communication system : Block diagram of communication system and comparative study of analog and digital communication. 

2 Modulation(upward frequency translation) and demodulation (downward frequency translation) and the need for modulation: broad classification of modulation [linear (amplitude-AM) and exponential (frequency-FM and phase-PM)]

3 Generation of double side band (DSB) with carrier, double side band with suppressed carrier (DSB-SC) and single side band with suppressed carrier: De-modulation of double side band with carrier –incoherent detector or envelope detector, peak diode detector, coherent or synchronous detection of DSBSC and single side band with suppressed carrier.

4 Superhetrodyne Receivers : Characteristics , Intermediate Frequency and its advantages, image rejection of the Receiver. 

5 Generation of FM signals(direct and indirect methods) and Demodulation.

6 Noise: Different types of Noise, SNR in AM, FM and PM System and use of emphasis Circuit in FM for SNR optimization. 

7 Analog pulse modulation : PAM, PWM, PPM and demodulation; comparative study of various analog pulse modulation
