What are the names of these blocks in the current Simulink r2024b

I saw these three blocks in a literature published in 1995, but I can't find the corresponding blocks in the new version of Simulink. Does anyone know their current names?

Hi @Darcy,

I believe the first two blocks could be the ramp and step block. Although, the third block can resemble the 'triggered subsystem' block's behavior, which could explain the second input signal as a trigger.

My guess: First one is a ramp block, second one is a step block, third one is a step block again but the step is done from time 0.

I agree about ramp and step.

I am not so sure on the third one.
