- Condense time-series signals
- License: Freeware
- Price: 0.00

This a very simple function that produces a condensed, approximate version of the time-series signal y, with each group of n adjacent points in y replaced by its average. You can use this to condense over-sampled signals so that subsequent processing will be easier and faster.

- Baseline Fit
- License: Freeware
- Price: 0.00

Baseline Fit each column in "x". There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput. Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated from selected points and then applied to the data.

- Pulse Waveform Delineator
- License: Freeware
- Price: 0.00

Arterial blood pressure waveforms contain rich pathophysiological information; hence receive much attention in cardiovascular health monitoring. To assist computerized analysis, an automatic delineator was proposed for the fiducial points of arterial blood pressure waveforms, namely their onsets, systolic peaks and dicrotic notches.

This function is written to understand and/or explain an fft algorithm and usage of radix2 procedure. This function take the signal which you want to find FFT, for m bit you can also call the function without entering a signal or number of points, because there is default values for y and m which are; y = sin(2*pi*50*t)+sin(2*pi*120*t); m=3; you can see the steps of order reversing used as built-in function but non others.

- Generate FM noise sidebands on a carrier using randn fn
- License: Freeware
- Price: 0.00

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected.
