Amplitude distortion occurs when(a) Impulse response is not constant(b

1.	Amplitude distortion occurs when(a) Impulse response is not constant(b) Impulse response is constant(c) Frequency transfer function is constant(d) Frequency transfer function is not constantThe question was posed to me in semester exam.My doubt is from Equalization topic in division Baseband Demodulation and Detection of Digital Communications
Answer» The correct choice is (d) Frequency TRANSFER function is not constant For explanation I WOULD say: When modulus of CHANNEL’s transfer function is not constant WITHIN W then AMPLITUDE distortion occurs.
