Fourier transform algorithm
no vote
Electric power industry, AC analog sampling Fourier transform algorithm. Can effectively filter out harmonics, speed up the calculation time. In the power industry, after the current, voltage, etc. gathering up the exchange amount, depending on the value of sampling points per period, you can get current, voltage, frequency, active power, reactive power, it is power and power factor, as well as the subharmonic wave phase angle, and calculates high accuracy, strong anti-interference ability. Greatly facilitate the work of software developers.
