In this article was made the identification of dynamic systems first and second order more common in electronics such as low high pass filters order, pass-band filter direct current motor through structure auto-regression with exogenous variable. The proposed dynamical are initially modeled by a continuous-time transfer function using physical laws. Subsequently, step entry signal applied data ...

Project Abstract : Direct-Conversion is an alternative wireless transceiver architecture to the well-established super heterodyne, particularly for highly integrated, low power terminals. Direct-Conversion transceivers suffer from the imbalance of the I and Q paths. By using a complex low-pass filter topology instead of a conventional pair of real low-pass filters, this imperfection can be redu...

The circuits using current-mode (CM) building blocks have received considerable attention in many filtering and signal processing applications. Compared to their voltage-mode(VM) counterparts, the are attractive because of wider bandwidth, higher slew rate, lower power consumptions. In IC technology, it is desirable operate at low voltages which can be achieved by CM blocks. As a large number o...

This paper presents The Electromagnetic Interference effect from power line noise in Multi Speciality Hospital to Bio-Medical signals. The study includes the design of Bio-Medical signal Generating circuits that is used to eliminate the power line noise from the signal. The Bio-Medical system basically is a combination of Instrumentation Amplifier, High pass filter, Low pass filter, and Notch f...

The initial alignment of the Inertial Measurement Unit (IMU) is an important process of INS to determine the coordinate transformation matrix which is used in the integration of Global Positioning Systems (GPS) with Inertial Navigation Systems (INS). In this paper a novel alignment method for a disturbed base, such as a vehicle disturbed by wind outdoors, implemented with the aid of a Vondrak l...

A novel filter configuration for the analysis of harmonic musical signals is proposed. The method is based on inverse comb filtering that allows for the extraction of selected harmonic components or the background noise component between the harmonic spectral components. A highly accurate delay required in the inverse comb filter is implemented with a high-order allpass filter. The paper shows ...

Neuroimaging studies have found distinct patterns of response to different categories of scenes. However, the relative importance of low-level image properties in generating these response patterns is not fully understood. To address this issue, we directly manipulated the low level properties of scenes in a way that preserved the ability to perceive the category. We then measured the effect of...

This paper presents a kind of design method about the decimation filter design for high performance ADC application. It was implemented and validated by simulation using MATLAB tool and its complete architecture was realized using DSP blockset and Simulink. A two-stage decimation filter architecture which can reduce digital switching noise was also introduced in this design. The FIR low pass fi...
