Synthesis of Analog and Digital Filters in LabVIEW

The paper introduces the method of analog and digital filters designing. The direct approach to the designing of the approximating polynomial for Bessel low-pass with maximum flat group delay was used. The scheme of Bessel low-pass was implemented for the specified transfer function. The automated system for time, frequency and dynamic filter characteristics measurement was designed in graphic programming environment of LabVIEW 10
