What is Fast Fourier Transform in Matlab?
A fast Fourier transform (FFT) is a highly optimized implementation of the discrete Fourier transform (DFT), which convert discrete signals from the time domain to the frequency domain. FFT computations provide information about the frequency content, phase, and other properties of the signal.
How to use conv function in matlab?
Description. w = conv( u,v ) returns the convolution of vectors u and v . If u and v are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials. w = conv( u,v , shape ) returns a subsection of the convolution, as specified by shape .
