INTRODUCTION: 

1BESC104C – Introduction to Electronics & Communication Engineering gives an overall introduction to the basic concepts of electronics and communication systems. The syllabus begins with power supplies and amplifiers, where we learn how AC is converted into regulated DC and how weak signals are amplified. It then covers oscillators and operational amplifiers, including crystal oscillators and their applications. The next module introduces communication systems, explaining how information is transmitted and received using concepts such as modulation. The syllabus then moves to digital electronics, covering number systems, logic gates, Boolean algebra, combinational and sequential circuits, flip-flops and counters. Finally, it introduces embedded systems and microcontrollers, showing how hardware and software are combined to create practical electronic applications. Overall, the subject helps students understand the journey from basic electronic circuits and signal processing to communication, digital systems, and embedded applications.
