Design of nonlinear-phase FIR filters with second-order cone programming
J.O. Coleman, Dan P. Scholnik · 2003
We extend classic linear-programming design of linear-phase FIR filters to second-order cone-programming design of nonlinear-phase FIR filters. Real and complex FIR filters with optional analog or digital cascade filters are designed using cones on discrete frequencies to approximate Chebychev, mean-absolute, and rms errors.
