3. The sinusoidal signal f(t) = a cos 2πfmt is applied to the input of a FM system. The corresponding modulated signal output (in volts) for a = 2V,fm = 4 kHz, is: q(t) = 10 cos(2 x 10't + 4 sin 2лfmt) across a 5002 resistive load. (a) What is the peak frequency deviation from carrier? (b) What is the total average power developed by (t)? (c) What percentage of the average power is by 10.000MHz? (d) What is the approximate bandwidth, using Carson's rule? (e) Repeat parts (a)-(d) for the input parameters a = 0.7 V, fm = 20 kHz; assume all other factors remain unchanged
