1.	Phase distortion is important in ________(a) voice communication systems(b) color video receivers(c) audio receivers(d) radio receptionI had been asked this question in semester exam.My doubt is from Bandwidth of FM Signal with Arbitrary m(t) in section Angle Modulation of Analog Communications
Answer» Correct choice is (b) color VIDEO receivers To elaborate: Phase DISTORTION is a change in the SHAPE of the waveform. It occurs when filter’s do not have a sharp CUT off frequency thus not properly filtering a wave. Thus, phase distortion is important in color video receivers.
