Abstract:

The design of linear-phase filters has assumed a role of increasing importance to the network synthesizer. Research is concerned with the design techniques for such filters by investigating the possibility of applying the potential anal gy to Bodes well-known method of parameter determination for linear-phase filters. The potential analogy is applied to 2 typical Bode filters the first has 3 critical frequencies in the transmission band and one in the transition region, while the second has 5 critical frequencies in the transmission band and 1 in the transition region. Flux plots for a negatively charged plate lying in the passband region of the frequency axis, and positive charges located in the finite p-plane, are drawn. The method of quantizing the negative charges on an equipotential is employed, from which a quantized image transfer function for each filter is obtained. The phase and attenuation characteristics of these transfer functions are studied and compared with similar characteristics of other linear-phase filter designs. Several realizing techniques are applied to these transfer functions and the resulting networks are shown. Author
