8 continuous-time fourier transform in this lecture, we extend the fourier series representation for continuous-time periodic signals to a representation of aperiodic signals. the basic ap- proach is to construct a periodic signal from the aperiodic one by periodically replicating it, that is, by adding it to itself shifted by integer multiples of an assumed period to. as to is increased the fourier series represents periodic, continuous-time signals as a weighted sum of continuous-time sinusoids. it is widely used to analyze and synthesize periodic signals. this lesson shows you how to compute the fourier series coefficients, or weights, from the signal. it also introduces you to the conditions that must be met for a signal

fourier series representation of continuous periodic signals pdf

Course Signals and Systems Eastern Mediterranean University. Since periodic discrete-time signals have a periodic and discrete-frequency transform, the dft, the fourier series is a special case of the dft. circular representation, circular shift, and circular convolution characterize the dft. thus, periodic or aperiodic signals can be represented and processed by the dft, which in turn is implemented very efficiently by the fast fourier transform … For periodic even function, the trigonometric fourier series does not contain the sine terms (odd functions) it has dc term and cosine terms of all harmonics..
