Principles of Communication Systems - I

This course introduces the fundamental concepts of communication systems required for modern engineering applications. It begins with essential mathematical tools such as Fourier Series and Fourier Transform for effective signal analysis. Learners gain an understanding of how information signals are represented in both time and frequency domains. The course explains basic analog modulation techniques including Amplitude, Frequency, and Phase Modulation. Each modulation method is presented with clear concepts and practical significance. The sampling process is introduced to explain the conversion of analog signals into digital form. Important principles such as the sampling theorem and Nyquist criterion are covered in detail. The concept of quantization and its impact on signal quality is also discussed. Methods for reconstruction of the original signal from sampled data are explained. Overall, this course builds a strong and essential foundation in communication engineering.
