For a complex exponential signal x(t) =2e^j2πt

(a) Suppose y(t) = e^jπt, would the sum of these signals z(t) = x(t) + y(t) be also periodic? If so, what is the fundamental period of z(t)?

(b) Suppose we then generate a signal v(t) = x(t) y(t), with the x(t) and y(t) signals given before, is v(t) periodic? If so, what is its fundamental period?
