Question: 24only a problem each of the following signals may be...

Question details

(2-4:only (a) PROBLEM: Each of the following signals may be simplified, and expressed as a single sinusoid of the form: A cos(or + ф). For each signal, draw a vector diagram of the complex amplitudes (phasors), and use vector addition to estimate the amplitude A and phase φ of the sinusoid. Then use the phasor addition theorem to find the exact values for A and ф. (a) ) 3 cos(3887T -4T/3) +cos(388T1 + 3t/4)
