Filter Analysis
DSP System Toolbox™ provides you with several filter analysis features to validate filter design specifications. You can use these features to visualize the various filter responses, such as magnitude, phase, impulse, and step responses. You can also determine filter properties using functions such as coeffs
, cost
, and info
, and verify filter characteristics using functions such as firtype
, isfir
, and isstable
. For a complete list of all the analysis functions that DSP System Toolbox offers, see Analysis Functions for Filter System Objects.
You can also visualize the magnitude and phase response of time-varying digital filters using the dsp.DynamicFilterVisualizer
object in MATLAB® and the Filter Visualizer block in Simulink®. For more information, see Configure Filter Visualizer.
