Frequency compensation of a vibration sensor digitally in a time domain by using a high-pass filter roll-off slope is presented. The subject matter reduces the noise floor of an analog front end or analog domain portion of a circuit configured to enhance the frequency response of a vibration ...
Also known as the discharge time constant (DTC), the larger the RC value, the lower the frequency response. The DTC also defines the sensor response to abrupt changes in sensor powering such as turn-on and signal overload. When the sensor is turned on or begins to recover from an over...
Equation 2 provides a simple, intuitive way to evaluate a design. As you reduce the height of the sensor enclosure, the stiffness increases and the mass decreases—therefore, the natural frequency increases. Also, as you increase the height of the enclosure, the stiffness reduces and the mass ...
The vibration sensor is also called apiezoelectric sensor. These sensors are flexible devices which are used for measuring various processes. This sensor uses thepiezoelectric effectswhile measuring the changes within acceleration, pressure, temperature, force otherwise strain by changing to an electrical ...

The frequency response of a sensor describes the value of the scale factor (KA), with respect to frequency. In a MEMS accelerometer, the frequency response has two primary contributors: (1) response of its mechanical structure and (2) the response of the filtering in its signal chain. Equat...
