Do we need a phase-locked loop?

The first 10% of the full text of this article appears below.

A phase-locked loop circuit compares the waveforms of input and reference electrical signals in terms of their frequency and phase. This type of circuit uses electronic feedback to adjust the frequency and phase of the input signal to match the properties of the reference signal. The frequency of changes to international radiation protection recommendations is often different from the frequency of their implementation into national legislation. There is also what could . . .
