The frequency-sampling method takes advantage of the linear relationship between the FIR filter coefficients and the frequency response to write the design problem as the solution to a system of linear equations. In this lesson you will learn how to use the frequency-sampling design method to produce filters with arbitrary magnitude and phase response. You will also learn how to avoid the potential problems with frequency-sampling designs. The frequency sampling method provides useful insight into the nature of FIR filter frequency responses.
