6. The message signal m₁ (t) is shown in the following figure and the message signal m₂(t) = sinc(2π × 10¹t), in volts again. (a) If m₁ (t) is frequency modulated on a carrier with frequency 106 Hz with a frequency deviation constant (kf) equal to 5 Hz/V, what is the maximum instantaneous frequency of the modulated signal? (b) If m₁ (t) is phase modulated with phase-deviation constant kp = 3 radians/V, what is the maximum in- stantaneous frequency of the modulated signal? What is the minimum instantaneous frequency of the modulated signal? (c) If m₂ (t) is frequency modulated with kƒ = 10³ Hz/V, what is the maximum instantaneous frequency of the modulated signal? What is the bandwidth of the modulated signal? m₂(1), V 105 0 3 4 1(sec)
