Determine Frequency Response of Zero Order Hold and First Order Hold using Actual Transfer Functions and Pade Approximations




Steps to perform the simulation

  1. At first enter the desired values of minimum frequency, maximum frequency and sampling time. Here default values are 1 for minimum frequency, 100 for maximum frequency and 0.1 for sampling frequency.

  5. Click on 'Plot' button for simulation.

  6. Click on the 'Download Plot' button to download the simulation results.

  7. Click on 'Clear' button before every simulation to clear the previous plot.

  8. To compare plots, select the desired options from the dropdown-menu without using the 'Clear' button.

  9. Place the cursor on the plot to read the exact values at any point for detailed analysis.

  10. Note: A maximum of four frequency response experiments can be conducted and plotted for comparison.
