Continuous and Discrete Fourier Transforms

Basic purpose of this lecture is to presentation on Continuous and Discrete Fourier Transforms. Discrete Fourier transforms converts a finite list of equally spaced types of a function in the list of coefficients of any finite combination regarding complex sinusoids, obtained by their frequencies, which has those same test values. It can be said to convert the sampled perform from its original domain on the frequency domain. Here also briefly describe: Infinite Fourier Transform, Uncertainty principle, FT & generalised impulse, Discrete Fourier Transform (DFT), Discrete Time Fourier Transform (DTFT) and Comparing signal by DFS, DTFT and DFT.
