a controller;

an analog-to-digital converter (ADC) coupled to the controller;

an anti-aliasing filter coupled to the ADC and configured to perform frequency filtering on the analog signal and provide the analog signal to the ADC; and

a randomly jittered sampling module coupled to the ADC and operable to provide a trigger input to the ADC, the trigger input causing the ADC to acquire a sample of the analog signal provided by the anti-aliasing filter;

wherein the randomly jittered sampling module is further operable to cause the ADC to acquire an aperiodic sequence of samples of the analog signal, the aperiodic sequence of samples having an amount of aperiodicity that is randomly generated; and

wherein the controller is operable to perform digital signal processing on the aperiodic sequence of samples to extract information from the analog signal and provide the information to an external system.
