Lock-in amplifier with phase-synchronous processing

摘要

The present device, a combination of lock-in amplifier-units (1) and phase-synchronous processing unit (2). This combination leads to a large number of valuable possibilities for the analysis and conditioning of signals. Among other things, these options (i) the extraction of time domain properties of the input signal, (ii) the extraction of statistical properties of the input signal, (iii) the extraction of frequency-space properties of the input signal and (iv) the preconditioning of the lock-in input signal.
