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.
