Abstract
The present invention is directed to a system and method which expands the applicability of subsampling to a larger range of signal repetition rates while reducing the range over which the sample rate must be tuned to accommodate a given signal. The resulting sample sequences are in the correct order, enabling direct display with an ordinary oscilloscope or other instrumentation. In one embodiment, a technique is used such that decimation of the samples also improves the response characteristics of the sensor. The system and method provides for a number of different procedures for sampling a signal of a given length. All other parameters being the same, the system allows more freedom in selecting the sample rate to correctly sub-sample a repetitive signal.
