L Bt -aZ Ye ay (THs) i, - 2 _—, aa, , 4.4 NETWORK FILTERS AND TRANSMISSION LINES, , , , 114, , DTP, 4-3, , RATIONALE, , The study of networks, filters and transmission lines leads to understanding of line communication,, audio and video communication, and microwave communication. Particularly the study of networks, takes off from principles of A.C. theory and introduces the student to parameters and characteristics, of various networks, including filters. Also the study of transmission lines becomes important as its, analogy is used in study of transmission of plane electromagnetic waves in bounded media., , LEARNING OUTCOMES, , After completion of the course, the students will be able to:, + describe the concept of symmetrical, asymmetrical, balanced, unbalanced, T, PI, ladder,, , lattice, L and Bridge T networks, , + demonstrate the operation of attenuators and filters., , * understand the concept and applications of transmission lines., , * measure standing waye ratio and characteristic impedance of the line, , DETAILED CONTENTS, , 1.
