The values of an AC noise measurement are collected from a large sample of the DUTs in a production lot. The average RMS reading is 0.12 mV and the upper and lower RMS specifi cation limits are 0.15 and 0.10 mV, respectively. The standard deviation is found to be 0.015 mV. What is the process capability and the values of Cp and Cpk for this lot? Does this lot meet six-sigma quality standards?
