In frequency modulation, what does Carson's rule determine? A. Carrier frequency B. Modulation index C. Bandwidth D. Phase deviation

According to Carson’s rule, Bandwidth B and modulating frequency fm are related as

Bandwidth of FM by Carson’s rule for the generation of FM,Carrier freq = 100MHz; Modulating signal freq = 1kHz; Max freq deviation = 50kHzSelect one:a. 1kHzb. 51kHzc. 204kHzd. 102kHz

A carrier wave of frequency 100 MHz is frequency-modulated by a sinusoidal wave ofamplitude 20 V and frequency 100 kHz. The frequency sensitivity of the modulator is 25kHz/V.(a) Determine the approximate bandwidth of the FM wave, using Carson’s rule.(b) Determine the bandwidth obtained by transmitting only those side-frequencieswith amplitudes that exceed one percent of the unmodulated carrier amplitude.

The modulation index of FM is given byA. Modulating frequency /Frequency deviationB. Frequency deviation/ modulating frequencyC. Modulating frequency/ carrier frequencyD. Carrier frequency / Modulating frequency

1. The minimum channel Bandwidth is used by which modulation technique?A. VSBB. DSB-SCC. FMD. SSB-SC
