R. Klempka, AGH University of Science and Technology, Faculty of Electrical Engineering, Automatics, Computer Science and Biomedical Engineering, Krakow, Poland The article presents an example of power supply system modernization in one of Polish steelworks. For the existing power system containing 3rd harmonics filters it was necessary to design a C-type filter for the 2nd harmonics. Two desig...

The Laplace transform of the functions tν(1+ t)β, Reν > −1, is expressed in terms of Whittaker functions. This expression is exploited to evaluate infinite integrals involving products of Bessel functions, powers, exponentials, and Whittaker functions. Some special cases of the result are discussed. It is also demonstrated that the famous identity ∫∞ 0 sin(ax)/xdx =π/2 is a special case of our ...

This paper presents the implementation of two stage FIR (Finite Impulse Response) decimation filter using system generator and it is compared with single stage implementation of FIR filter for WiMAX Application. FIR filter with decimation factor M is subdivided into two decimation factors M1 and M2. The two different FIR filters are designed with different coefficient values and different sampl...

This paper deals with the simulation of a Boost Power Factor Correction (PFC) Converter with Electro Magnetic Interference (EMI) Filter. The diode rectifier with output capacitor gives poor power factor. The Boost Converter of PFC Circuit is analyzed and then simulated with diode rectifier. The Boost PFC Converter with EMI Filter is simulated for resistive load. The power factor is improved usi...

FIR filtering is one of the most widely used operations performed in DSP applications. In this paper, a low power reconfigurable FIR filter is designed, in which the input data are monitored and the multipliers in the filter are disabled when both the coefficients and inputs are small enough to mitigate the effect on the filter output. Generally, since the amount of computation and the correspo...
