This article reviews the theory and implementation of the Bainter Notch Filter. Written and developed by Basin Street Design. This calculation examines the effectiveness of a Bainter notch filter such as the Bainter circuit as seen in the figure below [1]. Low-pass, high-pass, and standard notch responses can be realized. The following picture shows the […]
This article reviews the theory of the Wien Bridge Oscillator. Written to support his own practical projects by Basin Street Design. Here is the famous Wien Bridge oscillator circuit [1]. This picture is one shamelessly stolen from somewhere on the interwebs and modified for my purposes: The oscillator operates by sending part of its output […]
