Filter IIR
Ex: design an analog bufferworth filter that has a-2dB or better cutoff frekuency of 20 rad/sec and at least 10 dB of attenuation Solution Dik : Ω 1 = 20 rad/dt K 1 = -2 dB Ω 2 = 30 rad/dt K 2 = -10 dB Dari pers 7 diperoleh orde ==> n Dari pers (8) frek cutoff Untuk filter bufferwork LP ternomalisasi (Ω c = 1)dan n= 4 Lihat Tabel.
