This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...
Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
A higher channel separation stereo encoder built with 3 iC’s 4066, 4047, 4013 and 741. It has a filter L, C5 for frequencies higher than 15kHz and an extra audio amplifier built with 741. This stereo ...
