A signal m(t) is shown
This signal is applied to both phase modulator (with kp as phase constant) and frequency modulator (with Kf as frequency constant).
The ratio of kf/kp for same maximum phase deviation is _______?
  • a)
  • b)
    1/2π
  • c)
    1/π
  • d)
    ϖ
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A signal m(t) is shownThis signal is applied to both phase modulator (...
In phase modulation maximum phase deviation = kp∣m(t)Imax
Δϕ = 4.kp…(1)
In frequency modulation
Maximum phase deviation = 2πkf∫m(t)dt∣max
Given
The maximum phase deviation for both techniques is same
i.e., from (1) and (2)
Hence option B is correct.
