Butterworth and Chebyshev discrete filter designFrequency transformationsFIR window designMinimal realizationsAccording to the eigenfunction property of LTI systems, filtering changes the frequency content of an input signal. In the discrete-time domain, two types of filters designs are possible: the ...
Mechanical data were low pass filtered at 20 Hz using a dual-pass third order Butterworth filter. Stimulated data were subtracted from unstimulated data to yield a reflex trace. Mechanical reflex changes were analyzed within a 140–220 ms window post stimulus [4, 19]. Responses were considered ...
A digital filter with an Infinite Impulse Response (IIR), for example, is usually implemented using analogue equivalents, which are used to find the continuous time filter transfer functions that approximate the frequency domain specifications using well established methods such as Butterworth, Chebyshev...
The iterative method most widely used for solving set nonlinear equations and Symbolic Math Toolbox for Matlab features for finding numerical solutions are presented in detail. In the given examples, firstly a discrete Butterworth tan filter was designed by using transfer function poles in closed ...

Similarly, the frequency weighted function is chosen in a form of a high-pass Butterworth filter of order n f = 5 and cut-off frequency ω f = 0.1 (rad/s). Table 2 presents approximation errors for the analyzed models, in terms of M S E ω for ω > 3 (rad/s), H ∞ -norm ...
