WebNext ». This set of Signals & Systems Multiple Choice Questions & Answers (MCQs) focuses on “Periodic and Non-Periodic Signals”. 1. Given the signal. X (t) = cos t, if t<0. Sin t, if t≥0. The correct statement among the following is? a) Periodic with fundamental period 2π. b) Periodic but with no fundamental period. WebExplanation: Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. WebThe equation cos3t = t +1 has only one solution, t = 0, which is not a solution to cos2(t) = sin(t). So the curves do not intersect. But in general, if you discover that sint = (−1+ 5)/2 = α ...
