Descripción:

In one embodiment, a device for estimating frequency of the periodic signal includes a processor that receives a periodic signal and a periodic estimator module that is executable by the processor to estimate a length of a predefined number of cycles of the periodic signal with respect to a comparator signal to generate a length estimate for each of the predefined number of cycles, and store the length estimates. The periodic estimator module is further executable by the processor to sample the stored length estimates with replacement to generate resampled estimated vectors, and to calculate resample means for each of the resampled estimated length vectors, wherein each resample mean is the average of the length estimates in a respective resampled estimated length vector. The periodic estimator module is then executable by the processor to calculate a final periodic estimate of the periodic signal based on the resample means.
