For the signal, x(t) = log(cos(a*pi*t+d)) for a = 50 Hz, what is the time period of the signal, if periodic?
A. 0.16s
B. 0.08s
C. 0.12s
D. 0.04s
Answer:A
For the signal, x(t) = log(cos(a*pi*t+d)) for a = 50 Hz, what is the time period of the signal, if periodic?
A. 0.16s B. 0.08s C. 0.12s D. 0.04s
Explanation: Time period = 2*pi/(50)pi = 1/25 = 0.04s
