PCSA is a frequency domain analysis technique that can be used to transform PSDs (as those in a spectrogram) to the form of a two-dimensional histogram with frequency-magnitude bins. PCSA can be used to examine the spectral characteristics of a long period of data. It summarizes magnitudes and frequencies in the whole data sample into one 2D plot.

- Spectrogram Scope
- License: Shareware

SPECGRAMSCOPE makes it fairly easy to include a spectrogram scope in your real-time data acquisition and analysis application. You feed spectrumscope your data, and it plots the FFT - simple enough! It takes 2 steps to use SPECGRAMSCOPE. First, you initialize the scope with basic information needed for the FFT (sample rate, fft length, and history length). After that, all you need to do is pass your data to the scope..

- Using MATLAB for Bearing Fault Analysis
- License: Shareware

A ball bearing is comprised of an inner and an outer ring. A fault in each one of them can cause the resonance frequencies of the bearing to awake. This program has a simple GUI with which you can investigate bearing faults in the inner or outer ring. Using Signal Processing algorithms, you can view the activated frequecies, the frequecy-time spectrogram, the Kurtosis values and the signals in the fault and the system's reaction. This program is fully documented, along with an HTML to get you started..
