We present in this work the application of a set of diierent evolutionary methodologies in the problem of electronic lter design. The main objectives are to nd out which constraints in the lter topolo-gies, if any, must be observed along the evolutionary process and to study the problem of convergence to parsimonious circuits. The new area of Evolutionary Electronics is introduced, an evolution...

Technical, scientific or even simple documents presented online that involve mathematical expressions, issue a big problem with accessibility regarding visually impaired persons. One possible solution is to parse and interpret the mathematical contents and convert them into an audio format. This is a complex and multidisciplinary problem, which AudioMath [1], a work in progress at LPF-ESI [2], ...

Interest in human responses to whole-body vibration has grown, particularly due to the increasing usage of vehicles, e.g. cars, trucks, and helicopters etc. Another reason for growing interest in recent years is the importance of the vibrations generated by the performance of music for multimedia reproduction systems. There is a strong relationship between the frequency of the auditory stimulus...

In this paper, a supra-threshold spatio-velocity CSF experiment is described. It consists in a contrast matching task with a methods of limits procedure. Results enable the determination of contrast perception functions which give, for given spatial and temporal frequencies, the perceived contrast of a moving stimulus. These contrast perception functions are then used to construct supra-thresho...

Due to geometrical errors and possible misalignment of the sensors, wheel speed measurements provided by incremental encoders in road vehicles are usually affected by significant periodic noises. This paper presents an online wheel speed filtering procedure, based on a model of the sensor, aimed at processing the speed measurement to make it suitable for advanced vehicle dynamics applications. ...

Two iterative analysis algorithms were developed for the reoptimization of the LP synthesis filter based on a pulse-by-pulse reoptimization manner. In this study, the use of the pitch filter in the analysis algorithms is introduced. Similar to the no pitch case, improvement in the gain is achieved. On the other hand, this gain has dropped compared to the no pitch case. Moreover, the number of p...

A transformation called current-mode linear transformation (CMLT) and its filter applications using multiple output second-generation current conveyors (MOCCIIs) are presented. The systematic method is developed to realize CMLT MOCCII-based filters efficiently. Based on the proposed design tables, we can synthesize highorder current-mode all-pole and elliptic filters with MOCCIIs, grounded resi...

The lowpass systems with minimum higher order moments of the impulse response are presented. The optimization of the transfer function parameters is carried out for functions ranging from the second to the tenth order, with zeros at infinity. Besides the system order, no other requirements are set to restrict the frequency domain behavior of the system. Time and frequency domain properties of t...

A new three-input and single-output current-mode biquad filter using one plus-type inverting second-generation current conveyors (ICCIIs), two grounded capacitors and two resistors is presented. This filter can simultaneously realize five generic low-pass, band-pass, high-pass, band-reject and all-pass filtering signals. H-Spice simulations with 0.35μm process are used to validate filter feasib...

The traditional coplanar electromagnetic bandgap (EBG) structure is analyzed. The method is studied to lower the center frequency and broaden the bandwidth in this paper. A novel structure of U-bridged EBG power plane is proposed. The simulation and test results show that the bandwidth of the new structure is 4.32GHz, and the lower side cutoff frequency is at 380 MHz with the stopband depth at ...
