An accelerometer of sensitivity 10 mV/g is used to measure the acceleration of a vibrating beam. A DAQ system of 12 bit, 0-10 Vis used with a sampling frequency of 25kHz. An anti-aliasing filter is used with C₁ = InF, R = 1000, a. Find the minimum R, to prevent aliasing. b. If the measurement is required to recognize a minimum acceleration of 0.1 g, find the minimum R. V₁ Ra m R₁ w C₁ RE m V+ Op-amp Output (V)

Sample and Hold circuit

The sampling circuit and the holding circuit generate electrical samples as input and then hold these samples for a specified period. The time at which the sample and circuit holder produces the input signal sample is called the sampling time. Correspondingly, the length of the circuit that holds the sampled value is called the holding time.
