Short Time Fourier Transform using Python and Numpy
Code available here: github.com/KevinNJ Overview: The Short Time Fourier Transform (STFT) is a special flavor of a Fourier transform where you can see how your frequencies in your signal change through time. It works by slicing up your signal into … Continue reading

Sallen-Key Filter Design Using Simulated Annealing Optimization
Code can be found here: github.com/KevinNJ Overview: Sallen-Key filters are useful to design because they produce a second order filter response with a really small number of readily available components. Often times the low order of the filter is a good … Continue reading
