Question

What is the noise figure of merit for an SSB modulated signal?

(a) less than 1

(b) greater than 1

(c) 1

(d) 0.5

I have been asked this question during a job interview.

I'm obligated to ask this question of AGC in chapter Receivers & Transducers of Analog Communications

Answer 1

Correct choice is (c) 1

The best I can explain: Figure of merit is the ratio of output signal to noise ratio to input signal to noise ratio of a receiver system, oftenly used to describe the performance of a system. Figure of merit for SSB modulation is always 1.
