filter design and analysis -凯发k8网页登录

you can design and analyze a variety of digital fir and iir filters using dsp system toolbox™ functions and apps. some of these filters include advanced filters such as nyquist filters, halfband filters, advanced equiripple filters, and quasi-linear phase iir filters.

the design techniques compute the filter coefficients based on the specifications. the analysis techniques help you validate the specifications of the designed filter. analysis techniques include plotting the frequency response of the filter, finding the group delay of the filter, or determining if the filter is stable.

filter design and analysis are complementary and iterative. after you design a filter, analysis tools help you determine if the filter meets the required specifications. the toolbox provides design and analysis apps such as and . to learn how to use filterbuilder, see .

you can also transform filters from one form to another form using functions such as , , . to learn more about frequency transformations, see .
