Question
Problem 1.3 (Sinusoids and Exponentials) All signals are defined for -o < t < 00 (a) Sketch the sinusoid xa(t) = 2 cos(10rt + t/6). What is its fundamental period? (b) Repeat part (a) but for the sinusoid xb(t) = 5 sin(19rt – n/3). (c) What is the fundamental period of x.(t) = Xa(t) + xb(t)? HINT: It is not the fundamental period of Xa(t) nor xá(t). (d) Sketch the exponential xa(t) = e-l/5, What is its time constant? (e) Sketch the signal xe(t) = Xa(t)Xa(t). -
