question

The received signal at the end of a communication network is given by h(t) = 10 cos(10^6t + 200 sin500t). Determine a) the bandwidth (BW) of h(t); b) the modulating signal m(t) if h(t) is an FM signal c) m(t) if h(t) is a phase-modulated wave

options

  1. Bandwidth is approximately 10 kHz, modulating signal for FM is 2sin 500t, and for PM is 2cos 500t
  2. Bandwidth is approximately 32 MHz, modulating signal for FM is cos 500t, and for PM is sin 500t
  3. Bandwidth is approximately 1 kHz, modulating signal for FM is sin 1000t, and for PM is cos 1000t
  4. Bandwidth is approximately 64 kHz, modulating signal for FM is cos 500t, and for PM is sin 500t
  5. Bandwidth is approximately 32 MHz, modulating signal for FM is sin 500t, and for PM is cos 500t
  6. Bandwidth is approximately 32 kHz, modulating signal for FM is cos 500t, and for PM is sin 500t
  7. Bandwidth is approximately 100 kHz, modulating signal for FM is cos 1000t, and for PM is sin 1000t
  8. Bandwidth is approximately 32 kHz, modulating signal for FM is sin 500t, and for PM is cos 500t
  9. Bandwidth is approximately 1 MHz, modulating signal for FM is sin 500t, and for PM is cos 500t
  10. Bandwidth is approximately 64 MHz, modulating signal for FM is sin 500t, and for PM is cos 500t
