There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.

The circuit shown in Figure 1 is a complete adjustment-free linear variable differential transformer (LVDT) signal conditioning circuit. This circuit can accurately measure linear displacement ...

In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...
