Abstract: A method and apparatus measures flicker while improving the computational performance for measuring flicker severity level. Specifically, an Intelligent Electronic Device employs a method in which a processor summarizes and characterizes a plurality of instantaneous flicker sensation level values as histogram formatted data and selects a specific percentile of the instantaneous flicker sensation level values from the histogram formatted data. The method employed by the device uses the specific percentile to calculate a short-term flicker severity level value.

Abstract: Systems and methods that provide clock jitter compensation architectures that improve the performance of direct radio frequency (RF) receivers by injecting a calibration tone into the received radio frequency (RF) signals in order to help identify and then compensate for the clock jitter noise. After injecting the tone, the jitter noise going through the direct RF bandpass sampling receiver is estimated using a narrow bandwidth filter, and the received signals are further processed and demodulated depending on the Nyquist zone of the received signal. The relative modulation factor for the modulation is computed and then applied to the Nyquist zone to de jitter that particular Nyquist zone.
