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

Options

A. 10.62 MHz
B. 10.62 kHz
C. 5.31 MHz
D. 5.31 kHz

Answer

B

Explanation

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`
