Transmission Lines at Audio Frequencies, and a Bit of History

in frequency. Thus, at audio frequen-cies, a cable less than 2,000 ft long is no Fig 3 Electrical Wavelength at Audio Frequencies more complicated than its series resistance and parallel capacitance. As the cable becomes longer, or as frequency increases, the cable will begin to behave as a transmission line. References: 1. J. B.

TRANSMISSION LINE EQUATIONS A RADIO FREQUENCIES . There are two main forms of line at high frequency, namely • Open wire line • Coaxial line • At Radio Frequency G may be considered zero • Skin effect is considerable • Due to skin effect L>>R Coaxial cable is used as a transmission line for radio frequency signals, in applications such as connecting radio transmitters and …
Audio Frequency Transmission line? | All About Circuits

yes, transmission lines are used at audio frequencies, just check out all those at 60 and 50 hz. if you check into transmission line theory, it works the same, just that they call swr power factor, and power factor correctors are the same (with larger l and c components) circuits used in rf transmission lines. the power companies have to work with the wavelength at 60 or …
ac - Simulate RF transmission lines at Low frequencies ...
https://electronics.stackexchange.com/questions/128317/simulate-rf-transmission-lines-at-low-frequencies
I would like to simulate RF transmission lines in how they propagate, and how impedance mismatches at the end of the transmission line cause reflections and power transfer does not work. It would be nice if I could send an audio frequency through the "transmission line" and watch the output, hooking up different resistors until it is matched to ...
Interference with Radio, TV and Cordless Telephone …

Interference occurs when unwanted radio frequency signals disrupt the use of your television, radio or cordless telephone. Interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment. The two most common causes of interference are ...
Radio Interference - an overview | ScienceDirect Topics

1. General characteristics of radio interference from DC transmission lines. Similar to AC lines, the radio interference from DC transmission lines is high at low-frequency bands. As the frequency rises, the interference field strength attenuates rapidly. For frequencies higher than 10 MHz, the interference field strength becomes negligibly small.
