6 SPTool: A <strong>Signal</strong> Processing GUI Suite Pole/Zero Editor You can use the Pole/Zero Editor to design arbitrary FIR and IIR filters by placing and moving poles and zeros on the complex z-plane. Spectral Overlay Feature You can also superimpose spectra on a filter’s magnitude response to see if the filtering requirements are met. Opening the Filter Designer Open the Filter Designer from SPTool by either: • Pressing the New button in the Filters list in SPTool • Selecting a filter you want to edit from the Filters list in SPTool, and then pressing the Edit button The Filter Designer has the following components: 6-12
Filter Designer • A pull-down Filter menu for selecting a filter from the list in SPTool • A Sampling Frequency text box • A pull-down Algorithm menu for selecting a filter design method or a pole-zero plot display • A Specifications area for viewing or modifying a filter’s design parameters or pole-zero locations • A plot display region for graphically adjusting filter magnitude responses or the pole-zero locations • A Measurements area for viewing the response characteristics and stability of the current filter • A toolbar with the following buttons Icon Description Print and print preview Zoom in and out Passband view Overlay spectrum Turn on the What’s This help 6-13
