On Digital Systems with Negative Group Delay

Abstract: The investigations to be presented here have been motivated originally by a desired application of a subsystem with negative group delay as a part in the feedback path of a D/A-con verier. After a short description of this special problem we summarize the general properties of systems, having negative group delay in a certain band. The problem of designing FIR-and IIR systems with the desired properties will be discussed next. Five methods will be presented for the design of systems, the group delay of which a… Show more

“…One application of (6) is the design of all-pass fractional delay filters [18]. It is also used in one of several approaches described in [23] for the design of negative group delay systems. It should also be noted that if one sets in (5), then is an even function of .…”
