Abstract:In acoustic signal processing systems, it is required to measure the frequency of the received signal in real time. This paper utilizes a spectrum line ratio method to measure the frequency of the received signal for its real-time characteristic, simple structure, and high accuracy. Computer simulation is performed and the results verify the feasibility of the method.
Keywords:adding window  spectrum line ratio method  measuring the frequency of the received signal
