    Given below is the circuit diagram of an AM demodulator. For good demodulation of AM signal of carrier frequency v, the value of RC should be

    A) \[RC=\frac{1}{\upsilon }\]         

    B) \[RC<\frac{1}{\upsilon }\]

    C) \[RC\le \frac{1}{\upsilon }\]        

    D) \[RC>>\frac{1}{\upsilon }\]

    Correct Answer: D

    Solution :

    [d]: For good demodulation, \[\frac{1}{\upsilon }<<RC\] or \[RC>>\frac{1}{\upsilon }\]
