is now a function of time for both constant ζ and for ζ (t): . How ζ (t) varies over time depends on the ACL dynamics. The problem can be approached generally, without regard to oscillator type, by ...

Today, the majority of electronic circuits (including microprocessors, microcontrollers, FPGAs, and CPLDs) are based on clocked logic, requiring a timing source. Depending on the frequency accuracy ...
