New items are added on a daily basis as we get a lot of requests from readers to help design a circuit and explain how a circuit works. The Awfully Antique Audio Amplifier Homo Ludens While drawing a schematic diagram the other day, using my more than 20 year old CAD software, I started thinking. A rare occurrence, yes. This software is still DOS based, and attempts to directly write to the graphic card, printer, plotter, directly read the mouse, and so on. How to build 2nd Order Opamp Filters circuit diagram Three 2nd order filters are shown, low pass, high pass, and bandpass. Each of these filters will attenuate frequencies outside their passband at a rate of 12dB per octave or 1 4 the voltage amplitude for each octave of frequency increase or decrease outside the passband.
