摘要

The presented device is the combination of a lock-in amplifier unit (1) and a phase-synchronous processing unit (2). This combination leads to a multitude of valuable signal analysis and conditioning possibilities. Amongst others, these possibilities include (i) extraction of time-domain properties of the input signal, (ii) extraction of statistical properties of the input signal, (iii) extraction of frequency-domain properties of the input signal, and (iv) preconditioning of the lock-in input signal.
