WebWideband Frequency Modulation. As the name implies, wideband FM has wider bandwidth. It occupies a large portion of the FM signal and uses a wide range of frequencies. The advantage of using Wideband Frequency Modulation is its ability to transfer high data rates. Hence, it is commonly used in long-distance communication, … WebWideband FM (WBFM) Bandwidth For wideband FM, the frequency deviation contributes to the FM bandwidth. If the message signal is m(t), and the FM signal is ’ FM(t) = cos(2ˇf ct+ k fa(t)) where again a(t) = Z t 1 m(˝)d˝: If m(t) has a bandwidth 2BHz, then a(t) also has a …
WebMay 14, 2015 · The term WBFM is used in applications where the modulation index is equal to or larger than 1. However, in this article, we are going to address applications … WebThe DR is also the modulation index of the highest modulating frequency. If the DR ≥ 1.0 it is called wideband FM (WFM) and DR< 1.0 the modulation is narrow band FM (NBFM).
