The realization of the second-order universal (low-pass, band-pass, high-pass, band-reject, and all-pass) active current filter using a single second-generation current controlled conveyor (CCCII), two grounded capacitors, and one resistor is proposed in this paper. Three input signals and the bias current of the active element determine the filtering type of the output signals. H-Spice simulat...

in recent decades, research on the processing of grammatical structures in different languages has played a crucial role in psychological and linguistic studies. the present research aims to examine the extent to which arabic- and chinese-speaking learners apply passive voice and aspect in complement clauses in their pieces of writing. to that end, syntactic and pragmatic criteria of applying a...

This paper presents a new current-mode current-controlled four-input five-output universal filter employing one current-controlled current conveyor (CCCII), one electronically tunable CCCII and two grounded capacitors. The proposed configuration provides lowpass, bandpass, highpass, bandstop and allpass current responses that taken from the high-output impedance terminals, which enable easy cas...

A room may be used for a wide variety of performances and presentations. Each use places different acoustical requirements on the room. We desire a method of electronically controlling the acoustical properties of a room so that one physical space can accommodate various uses. A virtual acoustic room is a room equipped with speakers, microphones and signal processors that functions as an intera...

The Hummingbird is a small portable device which supports social awareness between people who frequent the same physical location. The Hummingbird uses wireless communication to give members of a group continuous aural and visual indications of which other group members are in the vicinity. Although many solutions for providing awareness information exist, they are either tied to the desktop (e...
