Amplitude modulated wave is represented by VAM=10 [1+0.4cos⁡(2π×104t)]cos⁡(2π×107t){V_{AM}} = 10\,[1 + 0.4\cos (2\pi \times {10^4}t)]\cos (2\pi \times {10^7}t) . The total bandwidth of the amplitude modulated wave is :

Multiple Choice Options

  • A 10 kHz
  • B 20 MHz
  • C 20 kHz
  • D 10 MHz

Step-by-Step Verified Solution

Bandwidth = 2 ×\times fm

= 2 ×\times 104 Hz = 20 kHz
