i want to measure frequency of a voltage signal having 6V rms. I have a cFP-AI-100 and the frequency to be measured is in the range of 50Hz. I used the Buneman Frequency Estimator PtByPt.vi and got different values of 'beta'[ The out put of Buneman estimator]. How can i get the frequency of the signal from 'beta'? i am here attaching the vi i had tried..
