Description

Principles of Communication (Part 1). Instructor: Prof. Aditya K. Jagannatham, Department of Electrical Engineering, IIT Kanpur.

This course covers fundamental concepts of communication systems, which are essential for the understanding of advanced courses in digital/ wireless communication systems. Beginning with various basic tools such as Fourier Series/ Transform, the course will also cover several important modulation techniques such as Amplitude Modulation, Frequency Modulation, Phase Modulation etc. Sampling process and Quantization, including Nyquist criterion and reconstruction of the original signal from the sampled signal will be dealt with in the later parts of the course.
