EXPONENTIAL FOURIER SERIES
Any “physically realizable”
periodic signal, with period To, can be represented over
the interval by the expression
The sum of exponential
functions is always a continuous function. Hence, the right
hand side is a continuous
function.
Technically, one requires
the signal, f(t), to be at least piecewise
continuous. In that
case, the equality does not
hold at the points where the signal is discontinuous
