What is the use of guard band provided in FM?
In radio, a guard band is an unused part of the radio spectrum between radio bands, for the purpose of preventing interference. It is a narrow frequency range used to separate two wider frequency ranges to ensure that both can transmit simultaneously without interfering with each other.
Why are guard bands used in FDM?
To accommodate the successful transmission of multiple signals over a single line, FDM separates assigned bands by strips of unused frequencies called guard bands. This prevents overlapping between signal frequencies over a shared medium.
What is meant by guard band?
Noun. guard band (plural guard bands) (radio) An unused part of the radio spectrum between bands, for the purpose of preventing interference. The unrecorded space between tracks on magnetic tape or other media which prevents the signals on adjacent tracks from interfering with each other.
Why guard bands are used in TDM?
A number of signals are sent simultaneously at the same time allocating separate frequency bands or channels to each signal. It is used in radio and TV transmission. Therefore to avoid interference between two successive channels Guard bands are used.
