The INTERPFT function does sinc interpolation by taking an FFT, padding its end with zeros, and then taking an IFFT. Essentially, INTERPFT resamples the signal after low-pass filtering it.Instead of putting all zero padding at the FFT *ends*, that padding can be split so that some are at the... Platforms: Matlab

THIS FUNCTION PLOTS FFT OF THE SIGNAL INPUT TO THE FUNCTION ISuserfft(input, sampling frequency, waveform, psd) input -> Input waveform sampling frequency -> Sampling frequency waveform -> 'real' refers to real baseband signals plots only half the fft output -> 'complex' refers to complex...

ButterParam - Fast parameters for a digital Butterworth filterThe calculation of filter parameters with BUTTER is expensive. Therefore ButterParam stores calculated parameters in a lookup-table to accelerate repeated calls with the same input.Example: x = rand(10000, 1); % test data [B, A] =... Platforms: Matlab

This GUI was designed to help users to better understand the Undersampling/Bandpass Sampling technique. While you're urged to follow the above link, to better understand this topic, a brief explanation follows:All of us, dealing with signal processing are familiar with the Nyquistd-deOCtShannon...
