In approximate and real time processing, one encounters the problem of making efficient use of the limited processing power available. Furthermore it can be desirable to enable a system to react dynamically to a change in requirements. For digital filters this implies the possibility of calculating filter coefficients on the fly with low complexity algorithms. Such an algorithm is presented for...

Symmetry is essential in the design of complex systems like Metaverse Transportation Sys-tem (MTS) and helps ensure that all components work together effectively. In development a microstrip diplexer for 5G-enabled IoT MTS, maintaining symmetry crucial to achieving flat responses with low group delays. By integrating transportation technology Metaverse, System can greatly improve effectiveness ...

Three traditional ASR parameterizations matched with Hidden Markov Models (HMMs) are compared to humans for speaker-dependent consonant recognition using nonsense syllables degraded by highpass filtering, lowpass filtering, or additive noise. Confusion matrices were determined by recognizing the syllables using different ASR front ends, including Mel-Filter Bank (MFB) energies, Mel-Filtered Cep...

Modulation transfer functions (MTFs) were measured with three different psychoacoustical paradigms in the same normal-hearing subjects. In the temporal-probe method, the threshold of a 4-ms probe tone (frequencies of 1000 and 4000 Hz) was measured at various envelope phases within a 100% sinusoidally amplitude-modulated (SAM) noise at modulation frequencies from 2 to 256 Hz. For the derived-MTF...

Feature extraction assumes a number of forms in a number of applications. In this paper, we improve feature extraction by not only increasing the number of quality features that one can extract but also ensuring that the features we do extract are, indeed, representative high-quality features instead of false, minute, or noise features. We show that higher frequencies do not, for the purposes o...

Control charts are one of the critical tools for process monitoring. Test statistics computed as a function sample means in control monitoring mean. In this study, these functions modeled by filters. These filters have essential properties both time and frequency domains. previous studies, only their domain been considered. Thus, resulting sub-optimal performance. This study investigates optima...

A compact microstrip lowpass filter with ultra-wide stopband characteristics and high suppression level is presented. To achieve compact size and wide stopband suppression along with improved impedance matching, symmetrically loaded resonant patches, open stubs and stair shaped high impedance stub are introduced in the filter. The measurement results show good agreement with the simulations. Th...

A newly developed ‘integrated services digital network’ (ISDN) splitter with bandstop (BS) topology is presented and compared to an actual ISDN splitter with a traditional lowpass (LP) topology. The LP-to-BS topology change reduced the amount of filter stages: a LP ISDN splitter requires an 8th order elliptic-like filter in order to be compliant to the standard ‘TS 101 952-1-4 V1.1.1’ [1] of th...

The potential for presynaptic information processing within the arbor of a single axon will be discussed in this paper. Current knowledge about the activity dependence of the firing threshold, the conditions required for conduction failure, and the similarity of nodes along a single axon will be reviewed. An electronic circuit model for a site of low conduction safety in an axon will be present...

This paper presents a new high-order universal filter structure with multiple-inputs and single-output. The structure only employs n second-generation current conveyors (CCIIs), n grounded capacitors, and n grounded resistors, which can realize nth-order universal filtering responses (lowpass, highpass, bandpass, band-reject, and allpass) from the same topology. Moreover, the proposed high-orde...
