A diode AM detector with the output circuit consisting of R = 1 kW and C = 1 μF would be more suitable for detecting a carrier signal of

Options

  1. A0.1   kHz
  2. B0.5   kHz
  3. C1   kHz
  4. D10 kHz

Correct answer

D. 10 kHz

Step-by-step solution

Given R = 1   kΩ or R = 1 × 10 3   Ω and C = 1   μF or C = 1 × 10 - 6   F . In this condition, frequency of carrier signal, 1 RC < < f c 1 1 × 10 3 × 10 - 6 < < f c ∴ f c > > 1   kHz Since, frequency must be greater than 1   kHz the possible answer will be f c = 10   kHz .
