Sums of Periodic Signals Example

adampanagos.org
This video examines the summation of periodic signals. We show that the summation of two periodic signals is not always periodic. Let T1 be the period of signal x1(t) and T2 be the summation of x2(t). We show that the signal y(t) = x1(t) + x2(t) is only periodic if the ratio of T1/T2 can be written as a rational fraction.

Hey, great video. Your way of showing where the condition comes from is super easy to follow and exactly what I was looking for.
Just a small mistake in the end, the equality should be T1/T2 = l/k and not T1/T2= k/l.
