The ratio detector design is superior to the Foster-Seely design in that:
A) it uses less diodes than does the Foster-Seely design
B) it offers superior linear response to wideband FM deviation
C) it can be built using digital integrated circuits
D) amplitude changes in the input FM signal have no effect on the output

Question

Quizplus · Accepted Answer

The ratio detector is known for its ability to demodulate frequency-modulated signals while inherently limiting amplitude variations, making it less susceptible to noise and amplitude fluctuations compared to the Foster-Seely discriminator. This characteristic ensures a more stable output unaffected by amplitude changes in the input FM signal.
