Capacitance Measurement Device With Reduced Noise |
摘要 |
A method or sensor arrangement for providing capacitive sensor detection with at least one capacitive sensor comprises a transmitting electrode and a receiving electrode. A stimulus at the transmitting electrode is generated and a signal is received from the receiving electrode and data packets are generated, each packet comprising a plurality of samples. The plurality of samples are weighted by providing less gain at a beginning and end of each packet with respect to a center of each packet; and the weighted samples are integrated to generate an output signal for each packet. |

1. A method for providing capacitive sensor detection with at least one capacitive sensor comprising a transmitting electrode and a receiving electrode, the method comprising:
generating a stimulus at the transmitting electrode, receiving a signal from the receiving electrode and generating data packets, each packet comprising a plurality of samples; weighting the plurality of samples by providing less gain at a beginning and end of each packet with respect to a center of each packet; and integrating the weighted samples to generate an output signal for each packet. |
