Sensor signal

Sensor signal is the process of changes in the output voltage due to load or pressure from a resistive transducer (sensor) which derive signal corresponding to an individual sensing element. The sensor signal handle sometime extremely small signals in the presence of noise (unwanted signal). So accurately measuring the changes in the output voltage due to load or pressure from a resistive transducer needs circuitry that provides the following electrical functions with accuracy: excitation, amplification, filtering, and acquisition.
