Analog Communications laboratory
Analog Communications lab is completely equipped with the hardware kits. This lab provides the information about the different types of modulators and demodulators used and types of techniques used for the processing of the analog (continuous) signals.
Laboratory-in-charge : Mr. K. Sandeep
Laboratory-Technician : P. Mohan Rao
Objective :
The main objective of this lab is to understand basic theories of analog communication system to design and implement analog modulator and demodulator and understand the applications of analog modulator and demodulator circuits, and to investigate signals in time and frequency domain. Students construct and analyze circuits on analog communication transmitter and receiver. Students conduct experiments to understand the signals available at different stages of AM and FM receivers. The objective of this course is to familiarize the students with different blocks in digital communication by constructing and then testing different digital modems and codec.
