Patent ID: 10801839

Abstract:
An accelerator comprises: an accelerometer (100), configured to detect an acceleration of a motion of a carrier and output a corresponding electrical signal; a sampling and low-pass filter (200), coupled to the accelerometer (100), and configured to sample the electrical signal regularly and filter a noise from the electrical signal; an amplifier (300), configured to amplify the electrical signal after filtering the noise; an analog-to-digital converter (400), configured to convert the amplified electrical signal into a digital signal; a function control module (500), configured to process the digital signal and output a control signal to control the analog-to-digital converter (400), the amplifier (300), and the sampling and low-pass filter (200); and an oscillator module (600), configured to output, according to the control signal, a sampling signal to the sampling and low-pass filter (200), so as to control the sampling and low-pass filter (200) to sample the electrical signal regularly.
