中文摘要 | 波形抽象學之功效近年來已獲中外學者之確認。它能更合理地取代抽樣之各種應用,在數位方面之應用更是特具功效。若干運算方面的改良在本文中將有闡述。不論在時域或在頻域均能達到節省電子計算機運作時間及使即時化得以實現。把千千萬萬在逆迴(convolution)及傅立葉變換中之函數用基本『常函數』來代表之。本文中之數距即係常函數之新觀念,將此一觀念充分發揮即可達成數學近似法之精確化及快速化。 |
英文摘要 | The Waveform Abstract (WA) is well known and appreciated internationally and domestically. It is a logical replacement for sampling, especially in digital applications. Some modification of operations both in time domain and frequency domain will be presented in this paper in order to save computer time and make most of the systems be real-time possible. The moments used in convolution and Fourier transform will be described as common functions, a new concept for fast and precise mathematic approximations [1]. |
