Compare the frequency responses with methods and for different sampling times            

Procedure

Steps to perform the simulation

  1. At first enter the coefficient values of the transfer function and sampling time T.

  1. Click on 'Clear' button to get results for new transfer function.

  2. Click on 'Download Plot' button to download the plot.

  3. Click on 'OK' button to clear the plot area.

  4. Note: Run both the methods one after the another to compare the responses.
