- Abstract
A real-frequency approach to the design of a diplexer having Butterworth or elliptic response is presented. The real parts of two minimum reactance functions are preassigned from the given transducer power gains. Their imaginary parts are derived by means of the rational Hilbert transform. Using a formula relating the derivative of a variable xk in an unknown vector X with respect to an entry in the coefficient matrix of a system of linear equations AX = B introduced in the appendix, the least pth method is adopted to implement the solution process, greatly reducing the highly nonlinear combination between the objective functions and the independent variables and resulting in a successful design of a diplexer approximating the Butterworth or elliptic response, both in the low-pass and the high-pass channels.
