You are recording the vibration of a steel cart. Your data acquisition system has a maximum sampling frequency of 10 KHz. Determine the Nyquist frequency at the maximum sampling frequency of your system. What is the maximum reportable vibration frequency based on SAE J211. If your data acquisition system was set to record for 1.0 second, what is the minimum frequency that you can accurately capture?
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.

NYQUIST FREQUENCY
The Nyquist frequency half of the sampling frequency. If your data acquisition system has a maximum sampling frequency of 10 kHz ( 10,000 Hz), then the Nyquist frequency is 5,000 Hz.
