A Fourier Transform-Based Frequency Estimation Algorithm.
IEEE Transactions on Instrumentation and Measurement(2018)
摘要
Nonsynchronous sampling conditions are the source of leakage errors in measurements based on digital signal processing. The optimal method to avoid such errors is to generate a synchronous sampling clock, whenever the input signal shows enough period stability to allow this. Such method, however, does not yield a straightforward evaluation of the input signal frequency, which is required in severa...
