Abstract:
The high resolution capture (HRCAP) of this invention enables time stamping of input signals with very high resolution without requiring high frequency sampling. This invention uses a capture delay line to time stamp an input edge signal as a fraction of the input signal sampling frequency. The capture delay line includes a first input receiving a synchronized signal and a second input receiving the input signal. These inputs propagate toward one another within a sequence of bit circuits. The meeting location within the sequence of bit circuits indicates a time of the input signal transition at a resolution greater than possible via the sampling frequency clock.
