Window creation class in c

The following C project contains the C source code and C examples used for window creation class. A class for creating Windows, Buttons, Edit boxes, and Multiline Edit boxes. It is very simple to use, and later I will add more types(Listbox, static(label), frame, etc). I included project files for Brland C++ Builder 5, and MS Visual C++ 6.

Scaled windowing function in matlab

The following Matlab project contains the source code and Matlab examples used for scaled windowing function. function to calculate window centered at the zero segment of outwind size WFUNC - windowing function from the list: 'barthannwin' 'bartlett' 'blackman' 'blackmanharris' 'bohmanwin' 'gausswin' 'hann' 'nuttallwin' 'parzenwin' 'triang' 'hamming' 'flattopwin' OUTWIND - length of the OUTPUT total window segment (padded with zeros if OUTWIND> INSIDEWIND or truncated INSIDEWIND if OUTWIND < INSIDEWIND INSIDEWIND - length of the windowing function centered in OUTWIND  

Signal rms in matlab

The following Matlab project contains the source code and Matlab examples used for signal rms. % Calculates windowed (over- and non-overlapping) RMS of a signal using the specified windowlength % y = rms(signal, windowlength, overlap, zeropad) % signal is a 1-D vector % windowlength is an integer length of the RMS window in samples % overlap is the number of samples to overlap adjacent windows (enter 0 to use non-overlapping windows) % zeropad is a flag for zero padding the end of your data.

Ferrigno&d'amico window in matlab

The following Matlab project contains the source code and Matlab examples used for ferrigno&d'amico window. These windows are obtained by the polynomial expression w(n)=(16(n/Ns-1))^4-8(n/8Ns-1))^2+1)^L 0<=n<=(Ns-1)/2 w(-n)=w(n) where w(n) is the nth value of the window (in the time domain) and Ns is the number of samples of the window itself.

Welchwin welch (parabolic) window function in matlab

The following Matlab project contains the source code and Matlab examples used for welchwin welch (parabolic) window function.  WELCHWIN Welch (parabolic) window  Usage:    w = welchwin(n) returns the n-point parabolic window     n: scalar window length     w: column vector of window values    Example:    t = (0:9)';    s = rand(1,10)';    n = length(s);    w = welchwin(n);    s2 = s.

This zip file contains functions related to apodization and symmetric window generation: 1) atomwin - Window based on atomic functions 2) barthewin - Barcilon-Temes window 3) conneswin - Connes window 4) coshwin - Hyperbolic cosine window 5) coswin - Minimum sidelobe cosine window 6) dchebwin - Dolph-Chebyshev window 7) denkwin - Denk window 8) dslepwin - Discrete Prolate Spheroidal Sequences (DPSS) window

Findfft returns fft amplitude and frequency vectors from input data in matlab

The following Matlab project contains the source code and Matlab examples used for findfft returns fft amplitude and frequency vectors from input data . findFFT returns fft amplitude and frequency vectors from input data, with options to return normal fft, zeropadded fft, windowed fft, or both windowed and zeropadded to remove spectral leakage.

Quick spectral analysis plots in matlab

The following Matlab project contains the source code and Matlab examples used for quick spectral analysis plots. Inputs:       data - the data for spectral analysis          K - averaging parameter, explained below       beta - beta value for the Kaiser window   out_form - spectral analysis option  samp_freq - data sampling frequency  Outputs:        out - calculated spectral estimate in form specified by out_form  Averaging Parameter:  The spectra are smoothed by averaging over windows 1/K times the full  length of data.

Short time fourier transform (stft) in matlab

The following Matlab project contains the source code and Matlab examples used for short time fourier transform (stft). %% function [t,frequency,Power_spectrum]=fft_s(y,windowlength) %% Inputs : % y: input raw signal % windowlength: window length to take fast fourier transform, it is a % factor of smapling frequency for example one can enter a window length % half of the sampling frequency by enteríng 0.
