A massage signal of frequency 3kHz3kHz is used to modulate a carrier signal of frequency 1.5MHz1 . 5MHz. The bandwidth of the amplitude modulated wave is

Options

  1. A6MHz6MHz
  2. B6kHz6kHz
  3. C3MHz3MHz
  4. D3kHz3kHz

Correct answer

B. 6kHz6kHz

Step-by-step solution

The relation between bandwidth and the signal frequency is given by

Bandwidth = 2 \times signalfrequency . . . \left(1\right)</p><p>Substitutethevaluesoftheknownparameterintoequation(1)tocalculatetherequiredbandwidth.</p><p></p><p>Substitute the values of the known parameter into equation (1) to calculate the required bandwidth.</p><p>\begin{cases}Bandwidth & = & 2 \times 3kHz \\ & = & 6kHz\end{cases}
