Abstract
Systems and methods are provided for evaluating physiological signal quality. A physiological signal, based on a series measurements on a subject, may be received. A quality of the physiological signal received may be evaluated, and an analysis of the physiological signal may be based at least in part on the quality evaluation.
Claims20
A method for evaluating signal quality, the method including the steps of:
- a. receiving, by a processor, a physiological signal based on a series of measurements on a subject;
- b. evaluating, by the processor, a quality of the physiological signal received comprising estimating a noise-free signal power and estimating a noise power for the series of measurements;
- and
- c. basing, by the processor, an analysis of the physiological signal at least in part on the quality evaluation comprising evaluating the signal quality of the series of measurements based on the estimated noise-free signal power and the estimated noise power.
