1 . Four frequencies are applied at the input of a non-linear amplifier. Write down all of the frequency components at the output of the non-linear device. Write down only the first three harmonics.
2. Find out the frequency components at the output of a resonant-tuned circuit tuned at 1200 KHz with a bandwidth of 15 KHz and connected at the output of a non-linear amplifier (mixer).

1. An AM signal has an unmodulated carrier voltage VC = 10VP, a load resistance of RL = 10, and a modulation index of m = 1. Determine:
Modulation
(a) PC = Vc2/2/2(10)=
PSB =PT-PC/2=
(b) Total power in the AM signal
2. Find the modulation index corresponding to the given trapezoidal pattern for the AM signal.
3. You are tuned to an AM station at 1200 KHz. Write down the frequency components of the received AM signal.
4. Draw an AM signal for the given conditions:
(a)
b) m>1
c)m
