1) For frequency modulation, of x(t) is linear to the signal s(t).
a: Amplitude
c: Instantaneous frequency
b: Excess phase d: None of above

Respuesta :

Answer:

Number "C" is correct

Explanation:

In frequency modulation (FM), the instantaneous frequency of the modulated signal is linearly proportional to the message signal \( s(t) \).

The correct answer is:

c: Instantaneous frequency
