%% FVTool Figure Handle Commands % Start FVTool from the command line. Display the magnitude response of a % 6th-order elliptic filter. Specify a passband ripple of 3 dB, a stopband % attenuation of 50 dB, a sample rate of 1 kHz, and a normalized passband % edge of 300 Hz. %% [b,a] = ellip(6,3,50,300/500); h = fvtool(b,a); %% % Display the phase response of the filter. h.Analysis = 'phase'; %% % Turn on the plot legend and add text. legend(h,'Phase plot') %% % View the all the properties of the plot. The properties specific to % FVTool are at the end of the list. get(h)
