Abstract :
Expressions for the bandwidth and the output to input signal/noise ratio in quasisingle sideband f.m. are derived as a function of the modulation index and the peak input amplitude to the exponentiator, to show that q.s.s.b. f.m. provides higher demodulation gains, while requiring approximately the same bandwidth as s.s.b. f.m.
