Resumen:
The application of a random sampling
strategy in high-frequency digital lock-in amplifiers
is proposed. This strategy allows reducing the
sampling frequency with reduced aliasing effects.
Analytical and numerical analyses that show the
advantages and limitations of the proposed scheme
are presented. The maximum operating frequency is
limited by the quantization of the random time
periods and the sample-and-hold device.
