Abstract	This paper aims to propose a simple way to detect the frequency of electrical signals based on zero-crossing point algorithms. First, by using Fourier algorithm as a digital filter to fetch the base band Sine and Cosine portions of signals, and then a zero crossing algorithm technology is applied to sine or cosine signal to calculate the frequency of the sine wave signal. It is intended to apply this theoretical development in personal computers to analyze the operation of the extracted signal. However, this computer must be equipped with DAQ (Data Acquisition Card) device and SCADA-based software Lab VIEW to filter the acquired signals stored in memory and then determines the signal frequency by the zero-crossing point algorithms. This developed system can be simulated with a high-order harmonic generation and noise signal source, and the program can be used to estimate the frequency of base band sinusoidal signals. Experiments show that the zero-crossing point algorithm is an effective method of measuring the frequency.
