An ECG/EEG common mode rejection ratio analyzer.
An ECG/EEG common-mode rejection ratio analyzer is discussed and its method of operation is analyzed. In addition to easily performed common-mode rejection ratio tests, this instrument also can perform linearity, frequency response and sweep-speed tests. Because of the complexity of the standard method for performing common-mode rejection ratio tests, many hospitals are omitting this test or employing alternative common-mode rejection tests. However, the ease of this new device facilitates its use in performing common-mode rejection tests.
