Exercise 5. Butterworth Filters The Matlab signal processing toolbox has an overwhelming array of options for designing and implementing filters, but for many geo-scientific applications we can use very simple filters. In this exercise we are going to explore the properties and use of a Butterworth IIR digital filter - Butterworth Filters 24-9.61r .87r 7r.2ir .6ir .8ir iT TRANSPARENCY 24.13 The pole-zero plot associated with the squared magnitude function for the desired Butterworth filter and the steps involved in the determination of the discrete-time filter. TRANSPARENCY 24.14 Frequency response for the discrete-time filter obtained by mapping a I am trying to filter out the noise from an array of wrist position data which is in degrees and was taken at 50 Hz. This is my first time using MATLAB, and this is not my area of expertise at all. Compare classical Butterworth, Chebyshev, and elliptic designs. IIR Filter Design IIR vs. FIR Filters. The primary advantage of IIR filters over FIR filters is that they typically meet a given set of specifications with a much lower filter order than a corresponding FIR filter. This tutorial covers the basics of analog filter design. It addresses the basic filter types of Butterworth, Chebyshev, and Bessel. It shows the reader, step-by-step how to design lowpass and highpass filters. The countless pages of equations found in most books on filter design can frighten Butterworth filter The minimum attenuation as dB is usually given at certain frequency s. The order of the filter can be calculated from the filter equation (rad/sec) s H( ) dB N s H s As 2 2 10log1 10log ( ) s As N 2log log10/10 1 Slide ??
