A modulated signal is given by: y(t)=(5+m(t))cos(410) where the message signal m(t) is given by m(t)=4cos 2800 (a) What is the carrier frequency in Hz? (b) Are m(t) and y(t) energy signals or power signals? (c) Sketch a line spectrum Y(f) for the modulated signal, with frequencies and amplitudes labeled with numerical values. (d) What is the average power of the modulated signal? (e) What is the percent modulation? (f) What is the highest instantaneous power? (g) What is the peak envelope power? (h) What is the minimum envelope power
