This paper describes the finite impulse response digital filter (FIR) and infinite impulse response digital filter (IIR) Principles and procedures for the design, while using LABVIEW software will filter under different parameters of different amplitude and phase frequency characteristic curve for visual display, so that the filter is designed to be simple and understandable. By comparing different methods to achieve the filter amplitude-frequency and phase-frequency characteristic curves, obtained the advantages and disadvantages of each filter is filtering.
