Analytical design of digital nonrecursive maximally flat fractional Hilbert transformer
Soo‐Chang Pei, Peng‐Hua Wang · 2003
Recently, a generalization of the Hilbert transformer, the fractional Hilbert transformer, was defined and developed. In this paper, we propose a design of the FIR filter to realize the fractional Hilbert transformer based on the maximally flat approach. The impulse response is obtained explicitly. An efficient realization structure is constructed according to some properties of the impulse response.
