Math.Tests.RealToBoolean ​

Converts constant and time-varying Real signals to Boolean by threshold.

Connects a constant source with value 1.0 to a RealToBoolean block with threshold=0.5 and verifies that the output is true (1). A second RealToBoolean block is driven by a sine wave (amplitude 1) that crosses the threshold, so the Boolean output toggles between true and false over time.

Usage ​

BlockComponents.Math.Tests.RealToBoolean()
