The order of the filter

Xem 1-20 trên 41 kết quả The order of the filter
  • When order of the filter increases hardware resource optimization becomes the real challenge. Distributed arithmetic (DA) architecture is comparatively more competitive to any of the other architectures in gate efficiency and operating speed.

  • The objective of this study was to determine the head losses in several type metal body disc filters manufactured by domestic companies. In order to meet the objective, three different filter designs (L, LT and Y type), each at four different inlet and outlet pipe diameters, were used to measure the head losses at different flow rates in the laboratory.

  • The computational lexicalization of a grammar is the optimization of the links between lexicalized rules and lexical items in order to improve the quality of the bottom-up filtering during parsing. This problem is N P - c o m p l e t e and untractable on large grammars. An approximation algorithm is presented. The quality of the suboptimal solution is evaluated on real-world grammars as well as on randomly generated ones.

  • Using ROM decomposition method of DA architecture we can reduce ROM size, however complexity of system design still exists. Hence to study DA architecture in FIR filter design a lower order filter is designed. Decrease in the order of the filter affects the frequency response of the filter, but it is time being neglected.

  • Designed filter is excited with impulse signal. The first sample is assigned a value of one (impulse signal) and all other inputs from sample1 to sample7 are made zero. When ‘en’ signal is enabled filter starts the processing of accumulation of partial products. After N clock cycles, where N is the order of the filter

  • For the implementation of band pass filter as per the specification implementation of 161 order is necessary. Implementation of such a higher order using simple DA architecture requires ROM size of 2161 which is very large and practically not feasible to implement on FPGA. Even though it is possible to reduce the size of the ROM by utilizing symmetrical property of coefficients

  • The discussion about the manned spacecraft program was initiated at NASA in 1959. Only one year later, Dr. Kalman and Dr. Schmidt linked the linear Kalman filter and the perturbation theory in order to obtain the Kalman-Schmidt filter, currently known as the extended Kalman filter. This approach would be implemented in 1961 using an IBM 704 computer (running at approximately 4000 operations per second) for simulation purposes, and subsequently, in July 1969, for making the descent of the Apollo 11 lunar module to the Moon possible....

  • The magnitude and phase response of the designed filter is shown in Figure (1). The figure shows both reference filter response and response of the filter after coefficients have been quantized to fixed point representation. Order of the filter comes out to be 161 i.e. total 162 coefficients. Design of such a higher order filter is difficult task

  • This paper proposes a control system connecting for the grid-connected PV (Photovoltaic) system. The control structure includes two alternating flyback converters, a control unit for connecting PV system to the grid, filter circuits at input and output of the converters. The output voltages of two flyback converters having half sinusoidal wave are is converted to completely sinusoidal wave by unfolding converter with the grid synchronization. This control system monitors the load demand and generated power capacity of PV in order to regulate power getting from the grid.

  • There is reason to expect strong genetic influences on the risk of developing active pulmonary tuberculosis (TB) among latently infected individuals. Many of the genome wide linkage and association studies (GWAS) to date have been conducted on African populations. In order to identify additional targets in genetically dissimilar populations, and to enhance our understanding of this disease, we performed a multi-stage GWAS in a Southeast Asian cohort from Indonesia. Methods: In stage 1, we used the Affymetrix 100 K SNP GeneChip marker set to genotype 259 Indonesian samples.
