It will help students understand the basics of signal and representation of signals by trigonometric Fourier series, signal transmission and analysis, Fourier transforms and their properties. It will enhance students’ knowledge about random noise processes. It will give them a detailed knowledge of modulation ad demodulation, analogue modulation techniques, carrier recovery schemes and phase-locked loops (PLLs). It will provide the knowledge of sampling theorem and reconstruction of signals. Also, an introduction to information theory, source coding, channel capacity, and communication channel models shall be discussed.[/vc_column_text][vc_custom_heading text=”COURSE LEARNING OUTCOMES (CLO)” font_container=”tag:h3|text_align:left” use_theme_fonts=”yes”][vc_column_text]CLO: 1.
