Different concentrations of a set of alcohol solution were measured experimentally; the system measurement error is no more than 0.02 %.
The desired signal in the auxiliary antennas of guidance radar may cause Angle measurement error by using conventional adaptive sidelobe cancellation method.
The error analysis shows that the measurement error is caused by the noise of the accelerometer, discrete double integration, noise of beacon and frequency characteristic error.
The digital lock-in technique is used to rather extract the effective signal from the noise and reduce the measurement error.
External proficiency testing also provides an ongoing comparison of inter-laboratory measurement error.
The edge transition of pulses from incremental encoder can be detected with double frequency to improve measurement precision, and to avoid measurement errors and accumulative errors.
Objective To introduce the basic theory of linear measurement error model and apply it to medical research.
In other words, people with normal hearing can produce spurious responses during a hearing test that look like a mild hearing loss, a result consistent with measurement error.
