A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...

The HEF4046B is a phase-locked loop circuit that contains a linear voltage-controlled oscillator (VCO) and two discrete phase comparators that has a common signal input amplifier and a common ...

A rubidium standard, or rubidium atomic clock, is a high accuracy frequency and time standard, usually accurate to within a few parts in 10 11. This is still several orders of magnitude less than some ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...
