15.11. Filter Design and Analysis Tool

Filter Design and Analysis Tool (FDA Tool) is Graphic User Interface for designing and analysing filters. It is used to design FIR and IIR filters by entering the desired filter specifications, or by importing filter from MATLAB workspace or by adding, moving or deleting poles and zeros. After designing a filter, the response can be viewed and analysed in other Graphic User Interface tool named Filter Visualization Tool (FV Tool) linked with FDA Tool. The different types of responses that can be viewed are listed below:

  • Magnitude response

  • Phase response

  • Group delay

  • Phase delay

  • Impulse response

  • Step response

  • Pole-zero plot

  • Zero-phase plot
