Butterworth Filter - 02 - Normalized Filter

http://adampanagos.org Before considering design of a Butterworth filter with arbitrary cutoff frequency, we first analyze a Butterworth filter with a cutoff frequency of wc = 1. This filter is called the "normalized filter". We examine the poles of such a filter in the s-plane. This normalized filter is the building block for designing Butterworth filters with arbitrary cutoff frequency and gain design criteria (investigated in the next videos).
