Finding the frequency components of a Qucs Output.

Fig 1: Initializing the Python Fourier Transform Program

Tonight’s post is again about the harmonic frequencies present in waveforms that are not simple sine waves. I needed a way to analyse the outputs of the circuits we were simulating in Qucs. To do that I had to create myself a tool. I wrote a

The current through the Parallel LC circuit for several resistance loads.

I posted the third of the videos tonight on how I create the graphs I use on this web site. Part 1 is the actual graphing software. Part 2 showed some additional Veusz features and how CSV files work and some “gotcha’s” about
