This paper describes a new class of maximally at lowpass recursive digital lters. The lters are realizable as a parallel sum of two allpass lters, a structure for which low-complexity low-noise implementations exist. Note that, with the classical Butterworth lter of degree N, which is retrieved as a special case, it is not possible to adjust the delay (or phase-linearity). However, with the mor...

Traditional continuous-time filters are of integer order. However, using fractional calculus, filters may also be represented by the more general fractional-order differential equations in which case integer-order filters are only a tight subset of fractional-order filters. In this work, we show that low-pass, high-pass, band-pass, and all-pass filters can be realized with circuits incorporatin...

abstract our religious teachings show a bridge on hell that in the hereafter, all will inevitably pass over it. the bridge path is very slippery and difficult to pass and has obstacles that each is called by particular name. peoplepass overit invariousforms. some fall to the depths of hell, some hop or suspend and a group pass quickly and easily.this paper studies and analyzes these teachings b...
