Abstract
The present disclosure relates to a system for sensing a signal. The system comprises a sampling unit configured to sample the signal, thereby recording a number of sampling points; a reference oscillator configured to provide a reference signal; an alignment unit configured to align the sampling points with the reference signal, thereby correlating each sampling point with a phase value of the reference signal at the respective sampling time of the sampling point; and a processing unit configured to generate a representation of the signal based on the correlation between the sampling points and the phase values.

A system, comprising:
- a sampling unit configured to sample a signal, and to record a number of sampling points;
- a reference oscillator configured to provide a reference signal;
- an alignment unit configured to align the sampling points with the reference signal, and to correlate each sampling point with a phase value of the reference signal at a respective sampling time of the sampling point, wherein the phase value is a measurement of a phase shift of the reference signal at the sampling time;
- and
- a processing unit configured to generate a representation of the signal based on the correlation between the sampling points and the phase values,
- wherein the sampling unit is configured to sample the signal at a sampling rate which is lower than twice the frequency of the highest frequency component in the signal, wherein the highest frequency component in the signal corresponds to a highest frequency of interest, and
- wherein each sampling point comprises a measurement value, and wherein the processing unit is configured to map the measurement values of the sampling points to the respective phase values based on a phase relation to the frequency of the reference signal.
