The common application of Impedance matching is in coupling an antenna with television. The antenna is a source because it provides the signal. ... For example, the resistance of antenna and cable is 75 ohms and the resistance of television is 300 ohms.

What is meant by impedance matching?
Impedance matching is designing source and load impedances to minimize signal reflection or maximize power transfer. In DC circuits, the source and load should be equal. ... In DC systems, the reactance is zero, so the impedance is the same as the resistance.
What are the impedance matching devices?
Impedance matching circuits are L network,pi network,split capacitor network,transmatch circuit etc. Impedance matching devices include coaxial cable balun transformer,matching stubs,quarter wavelength transformer,series matching section etc.
How do you calculate impedance matching?
How to use this impedance matching calculator?
- Choose the type of your circuit. ...
- Set the frequency to 110 MHz .
- Enter source resistance and capacitance, which are 50 Ω and 0 Ω , respectively.
- Repeat the same for load inputs - 150 Ω for the resistance and 0 Ω for the reactance.
- Type input Q factor as 2.5 .
Why is impedance matching needed?
Whether you are working with digital or analog signals, you'll most likely need to match impedances between a source, transmission line, and load. The reason impedance matching is important in a transmission line is to ensure that a 5 V signal sent down the line is seen as a 5 V signal at the receiver.
