Theory of resolutive signal space

CIn:Wuhan Daxue Xuebao (Ziran Kexue Ban), 1997,43(1) : 13~203 THEORY OF RESOLUTIVE SIGNAL SPACE I . Signal Reconstruction Wang Qiao (Department of Mathematics, Wuhan University, Wuhan 430072, China) A collection of instric concepts concerning the spectrum is built up in order to analyze the frequency domain of resolutive signal spaces. Both characterization theorem and metric function on shiftability is given. The signal reconstruction theorem is built for (irregular) sampling.
