Instead of choosing the response at a particular frequency in the passband as the desired response, the new criterion chooses the average passband gain as the desired response. The new criterion does not increase the design cost. Simulations show that the proposed criterion leads to better filters both in least square sense and in minimax sense.application/pdf132031 bytesapplication/pdfzh-TWDigital filtereigenfilterleast squares designDigital filter; Eigenfilter; Least squares designjournal article10.1109/LSP.2004.8240242-s2.0-2442466848
