Fast Algorithm for Short Time DFT Hilbert Transformers and Its Characteristics
タイトル(掲載誌)愛知工業大学研究報告. B, 専門関係論文集 = Bulletin of Aichi Institute of Technology. Part B
一般注記An ideal Hilbert transformer is realized as previously reported as the short time DFT Hilbert transformer by shifting the phase based on the concept of instantaneous spectra. Unfortunately, this ST DFT Hilbert transformer requires huge amount of computing power in analyzing instantaneous spectra, which becomes a severe problem on the developing stages. However, introducing the FFT structure makes possible to solve this problem to reduce the processing amount to allow to execute these processing on a single commercial DSP chip without degradation in its characteristics.
