INTRODUCTION TODIGITALFILTERS WITHAUDIOAPPLICATIONS

Accordingly, to get the most out of matlab, it is necessary to know some linear algebra [58]. The simplest lowpass filter of Eq.(1.1) is nonrecursive (no feedback), so the feedback coefficient vector A is set to 1.3.5 Recursive filters will be introduced later in §5.1. The minus sign in Eq.(2.1) will make sense after we study filter transfer ... ................
