FAQ
I want to measure vibration with an ADXL103/ADXL203 accelerometer and sample the analog output voltage with an AD7887 ADC at a rate of around 2.5kHz. The samples are then used to calculate an RMS value (based on 5000 samples). The bandwidth of the accelerometer…
Basically, a mass m has an associated matter wave frequency of sqrt (k / m), where k is a constant (for gravitational effects k = 2.7 x 10^17 Newtons/meter). If you plug in the value of the Earth's mass for m you get the frequency that is measured…
