    A diode AM detector with the output circuit consisting of\[R=1\text{ k}\Omega \]and\[C=1\text{ }\mu \text{F}\]would be more suitable for detecting a carrier signal of

    A)  0.1 kHz          

    B)         0.5 kHz

    C)  1 kHz                   

    D)         0.75 kHz

    E)  10 kHz

    Correct Answer: E

    Solution :

    Given   \[R=1\,k\Omega \] or       \[R=1\times {{10}^{3}}\]                 \[C=1\,\mu F\] or            \[C=1\times {{10}^{-6}}F\] In this condition frequency of carrier signal Because frequency is greater than 1. So      \[{{f}_{C}}=10kHz\]
