  • The page on Electronic Noise moved from Electronics->Test And Measurement to Electronics->Circuit Design.

  • Renamed the Fast Fourier Transform page to the Fourier Transform page, as it now contains information about other Fourier transforms.

  • Added graphs of 1D Fourier transformations:

and animated .gifs of 2D Fourier transformations:
  • Updated the pytest page with info on mark (markers) and pytest naming conventions.

May 2019 Updates

  • The Component Designators page was updated. The mobile unfriendly one-big-table design was removed in favour of separate sections for each component and designator/schematic symbol. Some of the symbols were also updated using InkScape.

  • The PCB Design Tools section of the main PCB Design page was moved onto it's own PCB Design Tools page.

  • All section on the main PCB Design page regarding PCB layers were moved into their own new PCB Layers page.

  • Big updates to the Convolution page, including the addition of a worked example where the convolution of two box-car functions is calculated.

An animated .gif showing the convolution of two box-car functions. The value of the convolution function at any time t (bottom line in red) is the amount area shown in red in the middle plot, which is the area under the curve of f(t)g(t) (the two waveforms multiplied together).
