Math.Tests.Tanh ​

Computes the hyperbolic tangent of constant and time-varying inputs.

Connects a constant source with value 0 to a Tanh block and verifies that tanh(0) = 0. A second Tanh block is driven by a sine wave (amplitude 3) that sweeps negative and positive values toward the saturation limits ±1.

Usage ​

BlockComponents.Math.Tests.Tanh()
