6.4.1 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 = 1 V, fm = 1 kHz, is: (t) = 100 cos (2π x 10't + 4 sin 2000πt) across a 50-ohm 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 at 10.000 MHz? d) What is the approximate bandwidth, using Carson's rule? Repeat parts (a)-(d) for the input parameters a = 0.75 V, fm other factors remain unchanged. = 2 kHz; assume all
