Hello everyone,

I need help in identifying this Simulink block in the link below. I can't seem to find it in any of the Simulink blocks. It could be a custom block but I don't know which or where to start creating it. Can anyone point me to the right direction?

Thanks!

Maybe:

tansig - Hyperbolic tangent sigmoid transfer function
elliotsig - Elliot symmetric sigmoid transfer function
Lookup Tables

Elliotsig is part of Neural Network Toolbox, but looks different (has an "E" top right corner)

Thanks! But most likely, I'll be using the tansig function. Thanks!

Looks like the Saturation block in (standard) Simulink. In the Discontinuities sub library.

I was experimenting on the different blocks in Simulink, I tried resizing the saturation block if it would look like the block I'm looking for but unfortunately, it's not it. I only have an image of that block from a thesis document, in which I'm trying to recreate. But thanks for the tips though! I'm new to Simulink and I'm currently doing this for my thesis.
