Before revision: The Pulse Transfer Function (PTF) represents the digital viewpoint of the continuous process , when interfaced with appropriate DAC and ADC for a specified sample time : Where denotes z-Transform for the chosen sample time .
After revision: The Pulse Transfer Function (PTF) represents the digital viewpoint of the continuous process , when interfaced with appropriate ADC and DAC, andis obtained as for a specified sample time : Where denotes z-Transform for the chosen sample time .
