To determine the frequency response of a continuous-time filter, the transfer function is evaluated at which is on the axis. Likewise, to determine the frequency response of a discrete-time filter, the transfer function is evaluated at which is on the unit circle, . The bilinear transform maps the axis of the s-plane (of which is the domain of ) to the unit circle of the z-plane, (which is the domain of ), but it is not the same mapping which also maps the axis to the unit circle.

Comparing my result with Matlab does look really nice: Then I tried it with prewarping, using: s = A ⋅ z − 1 z + 1, A = b tan ( b ⋅ T 2), b = 2 π ⋅ 100. This results in: With the warping the result doesn't look the same as with the matlab c2d-function. argument word meaning in malayalam
