AIM
To introduce the concept of realising circuits using active and passive devices for signal generation and amplification.

OBJECTIVES
i. To expose the students to study the different biasing and configurations of the amplifier circuits.
ii. To study the characteristics of tuned amplifier.
iii. To expose the students to various amplifiers oscillator circuits with feedback concepts.
iv. To learn the wave shaping process and circuits.
v. To learn and analyse the process of AC to DC conversion.
