A hybrid communication system uses both AMSC and FM. The information signal a(t) is first AMSC modulated with the subcarrier frequency 1000 Hz. Then it passes through an FM modulator with the carrier frequency 10Mhz. Its average power should be 50W, Kf is 2Hz/v, and a(t) = 2 cos (100pi*t).

What is the instantaneous frequency of the FM signal lamda_FM(t)

Write down the expression of the transmitted signal.

What is the approximate bandwidth of lamda_FM(t)

Explain clearly whether it is a narrowband or wideband FM signal?
