This is an odd function, so i try to find the fourier sine coefficient, with integral of sinx3sinkx. With appropriate weights, one cycle or period of the summation can be made to approximate an arbitrary function in that interval or the entire function if it too is periodic.

Here we recognize that the fourier transform has two singularities at z 0 and z i. Nel pensiero di fourier il falansterio doveva rappresentare lunita di base della nuova. In other words, when, the signal is compressed while its spectrum is stretched, and vice versa. In what follows we introduce the short time fourier transform stft and its applications to the analysis of signals. The fourier series expansion can be considered as one of the several different forms of the general fourier transform for periodic and continuous time signals, which states that a time signal can be decomposed not only in time domain in terms of a sequence of time samples, but also in frequency domain as well in terms of different frequency. So if a fourier transform doesnt exist because the integrals are infinite, laplace may still exist if the decaying exponential is strong enough, because the intergral of the attenuated function would converge.
