Abstract
A quasi-discrete Hankel transform (QDHT) is presented as a new and efficient framework for numerical evaluation of the zero-order Hankel transform. A discrete form of Parseval’s theorem is obtained for the first time to the authors’ knowledge, and the transform matrix is discussed. It is shown that the factor, defined as the products of a truncated radius, is critical to building the QDHT.
