Abstract

Frequency analysis is a common method for investigating physical phenomena or their signals. Many instruments based on FFT processors have been recently constructed to measure spectra. This paper is concerned with problems of the design and use of such tools and of developing some useful design formulas. After defining energy spectra, the importance of the Direct Fourier Transform (DRFT) method is pointed out and its error sources outlined. Some DRFT errors such as the variance due to input quantization. the picket fence effect and the variance of the DRFT spectral estimator, and their reduction, are dealt with in detail.
