Our difficulty arises from the fact that the polynomials appearing in table 1.1 , and as a consequence (1.25), are scaled for filters normalized to have w c = 1 , whereas (1.26) and the tables appearing in franco are scaled for filters. The design required 4 coupled sections. The final resul t shows that dimension of the filter is 76 x 40 mm. Designed topology is converted into band pass using standard transformation equations.

The final resul t shows that dimension of the filter is 76 x 40 mm. Waterloo, ontario, canada n2l 3g1. Based on filter order n (here 5) and using filter coefficients table as mentioned above for chebysev lpf for 0.5db ripple we will determine filter coefficients, which are g1=1.7058,g2=1.2296,g3=2.5408,g4=1.2296,g5=1.7058,g6=1. You can change the simulation parameters in the setup block. Fig1a.
