- Abstract:
- A different procedure, introduced previously by the authors for evaluating the errors due to the equally spaced sampling technique in the spectral analysis of a periodic signal and applied to the rectangular window, has been used to evaluate the effect of the cascade of two and three rectangular windows. This procedure is based on the assumption that the initial sampling instant can be randomized so that each estimated spectral component can be considered a random variable characterized by its statistical parameters. The theoretical expressions of these parameters were deduced and compared with those of the rectangular window; beside the theoretical findings were compared with the simulated ones denoting a very good agreement between them.
