A new programmable bandpass filter approach is presented. It is based on an array of fully differential transconductance circuits to control the filter parameters. The signal path does not contain any switch and fine-tuning of the filter parameters is implemented using programmable capacitors. The filter circuit is based on a biquad topology and designed with CMOS 0.18µm technology. SpectreS simulation results show a power consumption less than 5.2 mW with a ±0.9 V power supply. In addition, a wide frequency range (10-126 MHz) is achieved. The quality factor can also be tuned from 0.1 to 10.6.
The paper presents a specific sound design process implemented upon a collaboration with an important stakeholder of the wine (Champagne) industry. The goal of the project was to link sound properties with oenological dimensions in order to compose a sonic environment able to realise a multisensory experience during the wine tasting protocol. This creation has resulted from a large scale methodological approach based on the semantic transformation concept (from wine words to sound words) and deployed by means of a codesign method-after having shared respective skills of each field (sound and oenology). A precise description of the workflow is detailed in the paper, The outcomes of the work are presented, either in terms of realisation or conceptual knowledge acquisition. Then, future perspectives for the following of the work are sketched, especially regarding the notion of evaluation. The whole approach is finally put in the broad conceptual framework of 'sciences of sound design' that is developed and argued in the light of this study.
We propose in this paper a programmable bandpass filter based on an array of fully differential transconductance circuits that controls the filter parameters. The signal path does not contain any switch, and fine-tuning of the filter parameters is implemented using programmable capacitors. A digital building block is implemented in the proposed band-pass filter to tune its central frequency as well as its bandwidth. The filter circuit is based on a biquad topology, which is designed and implemented with CMOS 0.18 lm technology. Experimental results show a programming ability of the center frequency between 5.9 and 58 MHz, and the quality factor can be tuned from 0.36 to 10. These features are obtained for a total power consumption of less than 10.5 mW from a single 1.8 V power supply.
The Electronic Battle Box is an integrated suite of planning and decision-aid tools specially designed to facilitate Canadian Armed Force Officers during their training and during their tasks of preparing and conducting military operations. It is the result of a collaborative effort between the Defence Research Establishment Valcartier, the Directorate of Army Doctrine (DAD), the Directorate of Land Requirements (DLR), the G4 staff of lCdn Div HQ and CGI Information and Management Consultants Inc.Distributed on CD-ROM, the Electronic Battle Box contains efficient and user-friendly tools that significantly reduce the planning time for military operations and ensure staff officers a better focus on significant tasks. Among the tools are an OrBat Browser and an Equipment Browser allowing to view and edit military organizations, a Task Browser providing facilities to prepare plans using Gantt charts, a Logistic Planner allowing to estimate supply requirements applying complex calculations, and Road, Air and Rail Movement Planners. EBB also provides staff officers with a large set of doctrinal documents in an electronic format. This paper provides an overview ofthe various tools ofthe Electronic Battle Box.
