Vestigial side band signals are detected by ________(a) PLL detector(b

1.	Vestigial side band signals are detected by ________(a) PLL detector(b) Ratio detector(c) Square law demodulator(d) Synchronous DetectionI got this question in an interview for job.Question is taken from Need of Transducers topic in section Receivers & Transducers of Analog Communications
Answer» Correct answer is (d) Synchronous Detection The best I can explain: Vestigial side BAND SIGNALS are detected by Synchronous detection or coherent detection TECHNIQUE. The distortion in a VSB signal may be reduced by REDUCING the MODULATION index and increasing the width of VSB.
