Accurately measuring the amplitude of a sinusoidal signal is a design challenge that is common to many data acquisition designs. The most famous and ubiquitous solution to this problem is synchronous ...

Prepped for synchronous laser-beam detection applications such as print-start timers, the S9684 and S9684-01 photo ICs report highly stable digital outputs even when laser power or ambient temperature ...

The dual approach of digital and analog lock-in amplifier technologies has continued to advance the precise extraction of weak signals from noise-laden environments. These devices are indispensable in ...

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 ...
