Simulink programmable pulse generator The pulse generator included in Simulink does not provide the ability to programmatically set the parameters. This block provides inputs that allow the amplitude, pulse width, and pulse period to be set. It's fairly simple, but wasn't obvious to me so I thought I'd share it.
