Periodic signal is defined in the interval, by a certain time interval (cycle) repeated signal. With periodic signal, cycle, angular frequency, and satisfy the Dirichlet conditions, the periodic signal can be launched into a Fourier series can be expressed as a series of different frequencies of sinusoidal or complex exponential signal and. Fourier series has the triangular form and the form of two index
