Discrete

This sub-category contains twelve discrete components: Accumulator, Integrator, Unit Delay, Delay, Transport Delay, Rate Limiter, Differentiator, FIR Filter, Discrete Transfer Function, Discrete State Space, Hysteresis Function, and Low Pass Filter.

The Discrete sub-category provides several discrete calculation components. Their descriptions and supported features are given in Table 1.
