The estimated accuracy of phase and frequency of all phase FFT spectrum analysis and its
correction techniques are high [1-3], for its perfect characteristic of inhibiting the spectrum …

The traditional input data truncating way of spectrum analysis is improved and all phase FFT
(apFFT) spectrum analysis is put forward, we propose the realization diagram and analyze …

Based on the theory of all-phase spectrum, this paper analyses frequency and harmonics of
power. All-phase time-shifting phase difference correcting spectrum analysis is used to …

FFT algorithm is the popular software design for spectrum analyzer, but doesnpsilat work
well for parallel hardware system due to complex calculation and huge memory …

A new method for detection of aliased frequency components in fast Fourier transform (FFT)-
based spectrum analyzers and digital oscilloscopes has been developed. The basic system …

This paper based on the theory of all-phase spectrum, analysis the power harmonic signal.
All-phase spectrum uses time shifting and phase retardation correction method to correct the …

This paper describes the implementation of a 64 point FFT processor in VHDL. The
implemented architecture (E. Cetin, et al., 1997) is well suited for real-time spectrum analysis …

The conventional method of frequency measurement based on traditional fast Fourier
transform (FFT) can't provide to an ideal performance due to the fence effect and the leakage …

In this paper we firstly introduce the basic principle of FFT and analysis practical engineering
requirement of electrical network monitoring. Secondly, we build hardware platform based …

To perform FFT-based measurement in wireless communication analyzer, the frequency
range and resolution on the x-axis of a spectrum plot depend on the sampling rate and the …
