Dynamic signal processing

Abstract:

As part of a signal processing event, the maximum frequency of an input signal can be determined with a processor. The maximum frequency can be compared to a value generated with a decimator/interpolator. Based on the comparison, the sampling rate for sampling the input signal with the processor can be set as part of the digital signal processing event. The sampling rate can be adjusted as the frequency of the input signal varies during the signal processing event.
