Synthesis of Sharp 2-d Filters Using the Frequency Response Masking Technique
نویسنده
چکیده
In this paper, we present a new approach to realize sharp 2-D FIR filters using the frequency response masking technique. The synthesis of three common 2-D filters namely the diamond-shaped, fan-shaped and hexagonal-shaped filters are considered. Significant amount of complexity reduction (as compared to direct-form implementations) can be achieved for filters with very narrow transition bands. A design example is provided to illustrate the effectiveness of the approach.

Frequency-Response Masking Approach for the Synthesis of Sharp Two-Dimensional Diamond-Shaped Filters
The frequency-response masking (FRM) technique is an efficient method for realizing sharp one-dimensional (1-D) filters. Sharp 1-D filters realized using the FRM technique have considerably lower complexity than those realized in the direct form. In this paper, we present an extension of the FRM technique to the synthesis of sharp two-dimensional (2-D) diamondshaped (DS) filters. The new techni...

Sharp FIR filters have very high implementation complexities. This is even more so for sharp 2-D FIR filters. In this paper, we introduce a new efficient approach for the synthesis of sharp diamond-shaped 2-D FIR filters using the frequency response masking technique. The design procedure as well as the parameters for the minimum complexity design are presented. A design example is also include...
متن کاملDesign of sharp FIR bandstop filters using quadrature masking filters
A novel computationally highly e cient realization of sharp symmetrical bandstop FIR lter is proposed. The new structure is derived using the frequency-response-masking technique, where the bandedge-shaping lter is derived from half-band lter by substituting each delay of the half-band lter by M delays. The masking lters are unconventional. They are quadrature lters derived from linear combinat...
متن کاملA New Approach for Design Sharp Fir Filters Using Frequency Response Masking Technique
A new method to reduce the number of multipliers in the design of sharp FIR filter by frequency-response masking technique is presented. The success of the proposed method is based on a modified frequencyresponse masking approach where one of the subfilters in frequency-response masking approach is implemented by Interpolated Finite-Impulse Response (IFIR) technique. We have shown by example th...
