Description: The same method based on the impulse response of the IIR digital filter design, the same impulse response method is to use the design principles of digital filter unit sample response sequence of H (z) to approximate the impulse response of analog filters g (t). The same impulse response in accordance with the principles of law, through the analog filters of the system transfer function G (s), digital filters can achieve the system function H (z), the conversion steps are as follows: 1) using ω = ΩT (by relationship is derived), will, convert, Ω, and, unchanged 2) low-pass analog filters to solve the transfer function G (s) 3) the analog filter transfer function G (s) is converted to digital filter transfer function H (z).
