%% Plot 3-D Response of Omnidirectional Microphone % This example shows how to construct an omnidirection microphone % with response in the frequency range 20 - 20000 Hz and how to plot its % 3-D response over a range of angles. % Copyright 2015 The MathWorks, Inc. %% % Construct the microphone element. sOmin = phased.OmnidirectionalMicrophoneElement(... 'FrequencyRange',[20 20e3]); %% % Plot the 3-D response at 500 Hz. Show the response between -30 % to 30 degrees in both azimuth and elevation in 0.1 degree increments. plotResponse(sOmin,500,'Format','Polar',... 'RespCut','3D','Unit','mag',... 'AzimuthAngles',[-30:0.1:30],... 'ElevationAngles',[-30:0.1:30]);
