A carrier frequency of a station is 50MHz. A resistor of `10KOmega` and a capacitor of 10 pF are available in detector circuit. Is it good enough for detection?

Text Solution

Verified by Experts

Carrier frequency = `f_(c)` = 50 MHz
` = 50 xx 10^(6) Hz`
` R = 10 K Omega = 10^(4) Omega`
`C = 10 pF = 10 xx 10^(-12)`
`f = 10 pF = 10 xx 10^(-12)`
`f = 10^(-11) F `
`RC = 10^(4) xx 10^(-11) = 10^(-7) S`
` (1)/(f_(c)) = (1)/(f_(c)) = 2 xx 10^(-8) lt lt RC`
`therefore ` It is good enough for detection .
