This paper introduces a method for FIR digital filter design. To compute and plot by using the frequency-sampling method and MATLAB makes the design of an FIR digital filter convenient.
The digital logging instruments have many types and are different in plot format that makes difficult to build the data storage and nonstandard of the plot.
