The biological ECGs are fed into the device in form of digital signals, then the
measurement value can be obtained by calculation.
Test condition:
a) without NOISE
b)with 25uV high frequency
c) with 50uV peak to valley 50Hz/60Hz sinusoidal line frequency NOISE
d) with 1mV peak to valley 0.3Hz sinusoidal base-line NOISE
For each NOISE level above, the differences of measurements between the NOISE-free
ECGs and the ECGs with NOISE shall be determined. The two largest deviations from the mean
shall be estimated before calculation of mean and standard deviation of differences.
