Analogue Filter Design to Realize Simulation Based on MATLAB

The traditional analogue filter design process is complex,the computation work load is big,the filter characteristic adjustment difficulty,has affected its application.The article introduced one kind using the MATLAB signal processing toolbox (Signal Processing Toolbox) the fast effective design the conventional analogue filter design method which is composed by the software.Using the MATLAB design filter,may contrast the design request and the filter characteristic adjustment parameter as necessary,direct-viewing simple,enormous reduced the work load,is advantageous optimization which designs in the filter.
