A diode detector is used to detect an amplitude modulated wave of `60%` modulation by using a condense of capacity `250` picofarad in parallel with a load resistance `100` kilo ohm find the maximum modulated which could be find the maximum modulated frequency which could be detected by it

A

10.62 MHz

B

10.62 kHz

C

5.31 MHz

D

5.31 kHz

Text Solution

Verified by Experts

The correct Answer is:
B
For how pass filter, frequency greater than `(1)/(C)` can't pass through filter
`implies flt(1)/(C)`
`implies flt(1)/(RC)=4xx10^(4)Hz`
`=40KHz`
in given option maximum frequency below `40KHz` is `10.62KHz`
