In a diode AM detector with the output circuit consists of R=`1M Omega` and `C=1 pF` would be more suitable for detecting a carrier signal of

A

1MHz

B

0.1 MHz

C

0.5MHz

D

10MHz

Text Solution

Verified by Experts

The correct Answer is:
D
Here, `RC=10^(6)xx10^(-12)=10^(-6)s`
for demodulation, `(1)/(v_(c)ltltRC`
`v _(c)=(1)/(RC)` or `v_(c)gtgt(1)/(10^(6))=10^(6)Hz`.
`therefore v_(c)gtgt10^(6)Hz`
