Compare narrowband and wideband fm
Webaround the carrier. Such a FM wave has infinite bandwidth and hence called as wideband FM. The modulation index of wideband FM is higher than 1. The maximum permissible deviation is 75 kHz and it is used in the entertainment broadcasting applications such as FM radio, TV etc. Frequency Spectrum of a Wideband FM wave The expression for the ... WebBy using the above relations, we will get the NBFM equation as. s ( t) = A c cos ( 2 π f c t) − A c sin ( 2 π f c t) 2 π k f ∫ m ( t) d t. The block diagram of NBFM modulator is shown in the following figure. Here, the integrator is used to integrate the modulating signal m ( t). The carrier signal A c cos ( 2 π f c t) is the phase ...
