Difference Between Transmission line and Waveguide

Comparison Between Transmission line and Wave guide :




Transmission line
Wave guide
Small cross-section transmission lines (like coaxial cables) can only transmit low power levels due to the relatively high fields concentrated at specific locations within the device
Metal waveguides can transmit high power levels. The fields of the propagating wave are spread more uniformly over a larger cross-sectional area than the small cross-section transmission line.
Large cross-section transmission lines can transmit high power levels.
Large cross-section (low frequency) waveguides are impractical due to large size and high cost.




Difference Between Transmission line and Waveguide



what is Transmission line?

Answer:Transmission line:Definition: 

"A conductor or conductors designed to carry electricity or an electrical signal over large distances with minimum losses and distortion".




What is Waveguide?

Answer:Waveguide:Definition:

"A waveguide is an electromagnetic feed line used in microwave communications, broadcasting, and radar installations. A waveguide consists of a rectangular or cylindrical metal tube or pipe. The electromagnetic field propagates lengthwise. Waveguides are most often used with horn antenna s and dish antenna s".

Multiplexing and Multiple Access

Multiplexing And Multiple Access : Digital Communications Difference between Multiplexing and Multiple Access: Sr.No. Multiplexing Multiple Access 1 “In telecommunications and  computer networks, multiplexing is a process where multiple analog  message signals or digital data  streams are combined into one   signal over a shared medium.” “In telecommunications and computer networks, a channel access method or multiple access  method allows several terminals connected to the same multipoint physical medium to transmit over it and to share its capacity.” 2 The multiplexed signal is transmitted  over a communication channel,  which may be a physical transmission medium. A channel-access scheme is  based on a multiplex method  that allows several data streams  or signals to share the...
