Abstract

In this paper, a new algorithm for detecting the peak value of known-frequency sinusoidal signals is proposed. The proposed algorithm detects the peak value of a sinusoidal signal exactly and uses only two successive sampled data points for each peak value calculation. Hence, its transient response is only a sampling period. Simulation results show that this algorithm is applicable to detecting the peak value of steady-state, varying, and decaying sinusoidal signals. Therefore, this technique is very useful for digital systems in which the peak value of sinusoidal signals must be detected.
