Signal processing tips from Hackaday

Signal processing is an electrical engineering subfield that focuses on analysing, modifying and synthesizing signals such as sound, images and biological measurements. Electronic signal processing was first revolutionized by the MOSFET and then single-chip digital signal processor (DSP). Digital signal processing is the processing of digitized discrete-time sampled signals. Processing is done by general-purpose computers

Researchers want to redefine the threshold for scientific discovery from 0.05 to 0.005 — Quartz

https://qz.com/1055287/an-error-made-in-1925-led-to-a-crisis-in-modern-science-now-researchers-are-joining-to-fix-it/?utm_source=parVG In 1925, Fisher published Statistical Methods for Research Workers, whete he explained the concept of statistical significance. Somewhat arbitrarily, Fisher chose to define statistical significance as a difference that had less than a .05 probability of occurring by random chance (in technical terms, this is called a p-value).  Fast forward more than a century later,
