Optimization of a method to evaluate the fundamental frequency in real time
The problem studied in this paper and described in the literature is determining the fundamental frequency of a non-trivial signal in real-time. Using the gradient-descent algorithm, a new optimized method for fundamental frequency evaluation was proposed. The comparison between the two methods, classic and optimized, was carried out by utilizing a sine, square and amplitude modulated wave as input. In all cases, using the optimized method the system clearly performs better.
