Abstract
Sensor apparatus and methods for operating the same for measuring acceleration are disclosed. In some embodiments, circuitry inside a sensor digitizes a measured acceleration signal from an accelerometer into a digitized acceleration signal, which is processed by a digital equalization filter within the sensor to provide an equalized acceleration signal. The equalized acceleration signal may have a frequency response that is substantially flat over a frequency range that extends beyond the resonant frequency of a MEMs sensor within the accelerometer of the sensor.
