<strong>DESIGN</strong> <strong>AND</strong> <strong>ANALYSIS</strong> <strong>OF</strong> <strong>ANALOG</strong> <strong>FILTERS</strong>:<br />

Using a linear time scale from 0 to 10 s, overlay-plot on the<br />

same graph the unit step response of the Butterworth filter and<br />

the Gaussian filter.<br />

Overlay-plot on the same complex s plane graph the poles of<br />

the Butterworth filter and the Gaussian filter.<br />

Based upon the above graphs:<br />

(h1) In what ways does the Butterworth filter appear to be<br />

superior to the Gaussian filter?<br />

(h2) In what ways does the Gaussian filter appear to be<br />

superior to the Butterworth filter?<br />

Note: for each graph in parts (a) through (g), indicate which plot is for<br />

the Butterworth filter and which is for the Gaussian filter, properly<br />

label the x axis and the y axis for each figure, and include a title for<br />

each graph.<br />
