1.9 determine whether or not each of the following signals is periodic. If a signal is periodic, specify its fundamental period.
(a) x1(t) = jej10t
(b) x2(t) = e(-1+j)t
(c)x3(n) = ej7pin
(d) x4(n) = 3ej3pi(n + 1/2)/5
(e) x5(n) = 3ej3/5(n + 1/2)

1.10 Determine the fundamental period of the signal x(t) = 2cos(10t +1) - sin(4t -1)

1.11 Determine the fundamental period of the signal x(n) = 1 + ej4pin/7 - ej2pin/5

Thank you very much for this video, you are helping me get nice grades on my test

[pon]

I don't understand what you did at 2:50, why did you multiply it by (1-j)/(1-j)??

[gustavogutierrez]

In problem b you change the problem from e^(-1+j)t to e^-(1+j)t

Last Q 1 point 11 sir ny wrong likh lya h

N1 shi aya jb k N2=5 ay ga shi question ka


and lcm of 5 and 7 is 35 🎉
Ans is 35

[muhammadramzanpmc]

sir i think last question ka time period wrong h?

[AbdulRafay-rqom]

in last question fundamental time period would be 35
