Abstract: The present invention discloses a signal processing device, an air pressure sensor assembly and an electronics apparatus. The signal processing device for a sensing signal comprises: an input unit, which is configured to receive the sensing signal; and a processing unit, which is configured to attenuate a higher frequency component of the sensing signal so that the value of the higher frequency component when the sensing signal is stable is lower than that when the sensing signal is changing. According to an embodiment of this invention, the present invention can reduce the noise in a sensing signal from an air pressure sensor during a stable state.
