  • System and method for controlling learning period for adaptive noise cancellation
    Patent number: 9869667
    Abstract: A data acquisition system coupled to a mains power source and a method of operating the data acquisition system are disclosed. A test probe is configured to be coupled to a subject, and an analog to digital converter converts a signal from the test probe to samples. A noise replica generator generates estimates of noise in the samples, and a noise removal block removes from each sample an estimate of noise therein. When the subject is undergoing stimulation, the samples are provided to only the noise removal block. When the subject is not undergoing stimulation, the samples are provided to both the noise replica generator and the noise removal block.
