Outline of the Remainder

We first review Bode magnitude plots, and then design $ f^{\alpha}$ filters accordingly. We then evaluate the quality of the approximation, and develop a practical design algorithm. Discrete-time filter design using the bilinear transform with frequency prewarping is discussed. Finally, software implementations are given in the matlab and FAUST languages.
