Problems of 1 mark and 2 marks are grouped. One mark problems are simple and thus help in gradually learning the topic.
Transmission lines use two or more conductors for carrying electromagnetic waves. Most common are coaxial and two wire lines. Characteristic impedance (Z0) and propagation constant (γ) are important parameters. Voltage standing wave Ratio (VSWR) is one of the most important parameter.
Transmission line sections also find applications as various circuit elements like λ/2, λ/4 and λ/8 sections. Open and shorted transmission line sections are also used.
Various properties of transmission lines may be represented graphically. Most widely used is Smith chart.
