Разработка и анализ поразрядных устройств дискретного преобразования Фурье

Abstract

Для повышения быстродействия цифровых устройств спектрального анализа предложено использовать метод поразрядного вычисления ДПФ (ПДПФ). Проведен анализ предложенных поразрядных алгоритмов ДПФ. Разработаны схемы устройств поразрядного вычисления ДПФ. Проведена сравнительная оценка быстродействия устройств ПДПФ и БПФ. Полученные результаты доказывают преимущество предложенных методов и устройств ПДПФ по сравнению с БПФ.

We propose to use a DFT bitwise calculation technique for increasing the processing speed of digital spectral analysis devices. We carried out the analysis of the proposed bitwise DFT algorithms; worked out schemes of bitwise DFT devices; made a speed comparative assessment of the BDFT and FFT devices. The received results prove the advantage of the proposed BDFT techniques and devices as compared to FFT.
