  • Method and device for processing analogue output signals from capacitive sensors
    Patent number: 7054778
    Abstract: An analogue output signal of a sensor which comprises a carrier signal with a carrier frequency ?C which is modulated by a measurement size is sampled with a sampling frequency ?A to receive a sampled sensor output signal. The frequency ?A of the sampling signal is set so that it is an integer divisor n of the carrier frequency ?C, wherein the phase of the sampling signal is set so that the sampling signal is synchronous to the sensor output signal. The sampled sensor output signal is filtered now to remove periodically repeated signal components from the sampled sensor output signal. Then a filtered useful signal is received, wherein its amplitude is proportional to the measurand detected by the sensor.

  • Method and device for processing analogue ouput signals from capacity sensors
    Publication number: 20040174832
    Abstract: An analogue output signal of a sensor which comprises a carrier signal with a carrier frequency &ohgr;C which is modulated by a measurement size is sampled with a sampling frequency &ohgr;A to receive a sampled sensor output signal. The frequency &ohgr;A of the sampling signal is set so that it is an integer divisor n of the carrier frequency &ohgr;C, wherein the phase of the sampling signal is set so that the sampling signal is synchronous to the sensor output signal. The sampled sensor output signal is filtered now to remove periodically repeated signal components from the sampled sensor output signal. Then a filtered useful signal is received, wherein its amplitude is proportional to the measurand detected by the sensor.
