दूसरे क्रम के कम पास फिल्टर की आवृत्ति प्रतिक्रिया पहले क्रम के प्रकार के समान है, सिवाय इसके कि स्टॉप बैंड रोल-ऑफ 40 dB/decade (12 dB/octave) पर पहले क्रम के फिल्टर से दोगुना होगा।

दूसरे क्रम के फिल्टर की प्रतिक्रिया है:

Q1.In the design of Digital IIR Filters by means of Bilinear Transform, the design specifications are given. Match the following lists: List - I List - II P. N and Δf fixed 1. The design procedure has to start with the evaluation of the order of the filter necessary to meet the specifications in terms of the desired attenuation, transition bandwidth and  pass-band deviation. Q. Δf and δ fixed 2. The filter is completely specified and the transition bandwidth is directly obtainable during the design procedure. R. N and δ fixed 3.
