The dynamic characteristics of a sensor is the sensor's responsecharacteristics with the input that changed according to the time. And infrequency domain it is normally describes by the frequency responsefunction. The frequency response range is always limited, especially isthe main factor of the frequency response of the system. When thedynamic characteristics of a sensor are not ideal, such as non-smoothnessof the amplitude-frequency characteristic, non-linearity of thephase-frequency characteristic, we c...
