FIR filters are known to be stable and have a linear phase when symmetry properties. e.g., h[n] = h[M-n], are kept. A common FIR filter design method is the Parks-McClellan algorithm. In this algorithm, linear phase FIR filters which are optimal in the minimax sense, are designed. Theses filters have the form of H(omega) = A(omega)e(j(beta-omegaalpha)), where A(omega) is real, alpha is an integer or an integer plus 1/2 and beta is 0 or pi/2. These FIR filters are always symmetric: or antisymmetric. We introduce a simple procedure for designing Almost Linear Phase FIR filters, having a similar form of H(omega) but an arbitrary a, that are optimal in a similar sense. |
