Altair Compose: Signal Processing - Power Spectral Density

Altair Compose is an environment for doing calculations, manipulating and visualizing data (including from CAE simulations or test results), programming, and debugging scripts useful for repeated computations and process automation. Compose allows users to perform a wide variety of math operations including linear algebra and matrix manipulations, statistics, differential equations, signal processing, control systems, polynomial fitting and optimization.

Using Compose for Signal Processing allows useful information to be extracted from sensors that cannot be measured, can improve transmission, storage efficiency, and quality of signal. It will help you have a more clear understanding of phenomena in many applications.

The "Signal Processing" playlist has been organized in 13 modules covering amongst others fundamentals, file i/o, frequency domain as well as time domain analysis.

Thank you for your efforts to make this topic simple

Thank you for this.

You mention that for the Welch method, the number of segments is equal to the signal length divided by the window length. And you then write a version of this statement in your code defining WindowLength. However, since the Welch method overlaps segments, would it not be the case that if you had a window length of 1/10 length(s) with 50% overlap, in order to cover the full length signal pWelch would need to create 19 segments, since each additional segment covers 1/5 more of the signal?

Also, is the psdapp included in the Compose personal edition?
