A narrowband FM is the FM wave with a small bandwidth, The modulation index mf of narrow band FM is small as compared to one radian. Hence, the spectrum of narrow band FM consists of the carrier and ...

Abstract: The spectra of FM signals corresponding to various pulse shapes (of relevance in PCM work) are determined. The corresponding demodulated output pulse shapes in a limiter-discriminator ...
