Implementation of Band Pass Filter for Homomorphic Filtering Technique
In order to improve the performance of homomorphic filtering technique for face images, band pass filter is selected to replace the conventional high pass filter in homomorphic filtering technique. Apart from the noise reduction capability, the band pass filter is specifically designed for face images as it is based on the locations of illumination component in Fourier spectrum. The qualitative...
متن کاملDesign of Microwave Band-Pass Filters with Cross-Couplings
Cuvinte cheie. Filtre, microstrip, cuplaje încrucişate, optimizare. Rezumat. Articolul prezintă un studiu asupra posibilităţilor de îmbunătăţire a proiectării filtrelor trece-bandă de microunde cu cuplaje încrucişate, utilizând o procedură hibridă de optimizare. În acest fel toate caracteristicile filtrului, incluzând aici şi localizarea în frecvenţă a polilor de atenuare, pot fi precis control...
متن کاملThe Band Pass Filter
The `ideal' band pass ̄lter can be used to isolate the component of a time series that lies within a particular band of frequencies. However, applying this ̄lter requires a dataset of in ̄nite length. In practice, some sort of approximation is needed. Using projections, we derive approximations that are optimal when the time series representations underlying the raw data have a unit root, or are...
متن کاملA Design of Narrow-Band Band-Pass
C l c3 Abstract-In this paper, a design method is described for low-sensitivity narrow-band band-pass switched-capacitor filters (SCF's) using a pseudo-2-path principle and a capacitor-error-free voltage inversion. The proposed method is based on the low-pass to high-pass transformation using voltage inversion, the pseudo2-path principle, the capacitance-ratio reduction technique and a very low...
متن کاملPrinted Band-Pass Filter at L Band
* The authors are with the IMTEL Institute, Belgrade, Serbia and Montenegro Abstract – This paper presents a new concept of band-pass filters with capacitive coupled resonators applied for realization of a printed filter in L band. The significant size reduction achieved by the original construction allows filter realization at these very low microwave frequencies. The agreement between the pre...
