Wideband FM is used for FM broadcasting, in which music and speech are transmitted with up to 75 kHz deviation from the center frequency and carry audio with up to a 20 kHz bandwidth and subcarriers up to 92 kHz.

What is wideband FM signal?
WIDE BAND FM MODULATION:
For large values of modulation index mf, greater than 10 the FM wave ideally contains the. carrier and an infinite number of sidebands located symmetrically around the carrier. Such a FM. wave has infinite bandwidth and hence called as wideband FM.
What is wideband and narrowband FM?
Narrowband systems typically have lower data rate transmissions, whereas the wideband systems support relatively higher data rate transmissions. Wideband signals are generally greater than 1 MHz in bandwidth. More bandwidth translated into higher data rates, in terms of transmitted and received signal information.
What is wideband modulation?
The modulation technique used here is wideband frequency modulation. When the highest frequency component of a modulating signal is greater than the peak frequency deviation of modulated signal , then it is called as wide band frequency modulation.
What is wideband frequency?
Wideband in this context is usually considered to cover frequencies in the range of 50–7,000 Hz, therefore allowing audio with richer tones and better quality.
