Abstract
In industrial working condition, signals by an instrumentation with an optical sensor are inaccurate because of noise. If the signal and the noise are separated in the frequency domain, the noise can be reduced by filtering or using a cepstrum.In this paper, we produced two signals. In order to do this we connected two serial sensors thereby producing one signal. The other signal was produced by connecting the inverse of these two sensors. This method enables us to obtain a reliable signal without any noise on the signal line even if signal and noise could not be separated in the frequency domain. In this case “any noise” means under a quarter frequency of the analog switch.We propose to call this method alternating Noise Cancelling (ANC). The accuracy of the ANC method has been verified by examples using sinusoidal and other noises.
