Producing and manipulating the sine wave function is a common problem encountered by circuit designers. Sine wave circuits pose a significant design challenge because they represent a constantly controlled linear oscillator. Sine wave circuitry is required in a number of diverse areas, including audio testing, calibration equipment, transducer drives, power conditioning and automatic test equip...

Six computer-b...

Recently, the rapid advancement of IT industry has resulted in significant changes audio-system configurations; particularly, audio over internet protocol (AoIP) network-based audio-transmission technology received favourable evaluations this field. Applying AoIP a certain section multiple-cable zone is advantageous because installation cost lower than that for existing systems, and original so...

A point-to-point packet transmission system which integrates a fixed-bit rate, PCM coded, NTSC quality video signal and tu o multiplexed audio channels has been prototyped. The system consists of an Assembler Interface Card (transmit end) and a Disassembler Interface Card (receive end). At the Assembler Interface Card service equipment is connected in a daisy-chained architecture. Information i...

Electronic processing of audio signals is not new. Tone control by means of one or more analog filter stages is a well-known example from hi-fi technology the technology of the faithful reproduetion of speech and music. Another example is the improvement of audio quality by altering spatial perception with the aid of stereo effects and reverberation. The basic knowledge of acoustics and percept...

The characteristics of audio equipment are rarely studied in time domain, mostly in frequency domain. Although the characteristics in frequency domain are important, the primary way humans here sound is in time domain. The characteristics of an audio system in time domain should therefore be given more attention. In this paper, some common misunderstandings of the Fourier theory are discussed, ...

Distributed collaboration and webcasting applications are complex distributed applications that require control of multimedia equipment (e.g., cameras, microphones, switchers, projectors, audio systems, etc.) and processes that capture, play, and operate on audio and video streams. These applications typically use multicast communication protocols because data must be delivered to many particip...

For 30 years Disc Jockeys have been expressing their musical ideas with scratching. Unlike many other popular instruments, the equipment used for scratching is not built as one single unit, and it was not intended to be a musical instrument. This paper gives an overview of how DJs use their turntable, vinyl record and audio mixer in junction to produce scratch music. Their gestural input to the...

A/V over twisted pair is the transmission and distribution of audio and analog video, as well as control signals over wiring traditionally associated with data networking and telephone systems. This wiring is commonly known as UTP, or unshielded twisted pair. Special interfacing equipment is required to send video and audio signals over UTP wiring. UTP-based A/V systems are appealing for many a...

Advances in technology have led to the development of several implantable bone conduction devices (BCD) employing bone conduction stimulation for the treatment and rehabilitation of mixed and conductive hearing loss [1]. BCD are alternatives when the benefit of conventional prosthetic equipment is limited or contraindicated [1,2]. BCDs directly stimulate the inner ear by skull vibration [1]. Bo...
