摘要
提出一种基于改进的能量矩形平衡法的频率测量算法,给出框图程序。该算法将现代测量理论与能量矩形平衡法相结合,完善LabVIEW的信号处理功能。可应用于各种波形的频率测量,能有效地减小测频误差和抗噪。
A frequency measure algorithm based on the improved energy rectangular balance method was presented in this paper. The corresponding program was given. The algorithm which combines the theory of modem measurement with energy rectangular balance method improved the signal processing function of LabVIEW. It can be applied in measuring the signal frequency of waves and effectively decrease the measurement error.
