In the given detector circuit, the suitable value of carrier frequency is

A

`lt lt 10^9` Hz

B

`lt lt 10^5` HZ

C

`gt gt 10^9` Hz

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`1/(f_c)lt lt RC`
`RC =1000 xx10^(-12) =10^(-9) ` sec
`f=1/T =1/10^(9) = 10^9` Hz
`f_c` is much less than `10^9` Hz (say 100 KHz).
