how to find impulse and step response

[irish_sunset33]

hey every body,

i am kind of new to labview. i want to find the impulse and step response of a system in labview. how to i give input, to the impulse and step response vi's. can some body post the vi for me. just simple impulse and step response of a system.

bye

i just want the functionality, as depicted in this simulink diagram.also i want to find impulse response in this same manner.

thanks

LabVIEW has an Impulse Response Function (requires the Full Development System edition). There's also the Control Design Toolkit.

To obtain the same functionality in you PNG, you need the "Control Design and Simulation Module". This module allows you simulation dynamic systems in the "simulation" palette and design and analyze systems, in the "Control Design" palette. They are all available in the "Control Design and Simulation". This used to be two different products that were merged in LabVIEW 8.6.

For your example, you just need to go to the Simulation Palette and you will find of the blocks inside.

However, if you need to simulate a Impulse response, I would advice to look into the Time Response inside the control design palette, which has a function that will allow you to obtain the response directly since using Simulation woud need a high level of knowledge to get ut correctly
