Discrete

In the Discrete section of the basic library of blocks, you can simulate discrete-time systems by performing tasks such as delaying signals, calculating differences and derivatives, and filtering and controlling processes with PID controllers. These blocks allow you to accurately simulate a variety of discrete-time systems and processes using integration, signal transfer, and delay methods.

Delay: Delays the input signal for a fixed or variable number of calculation steps.
Difference: Calculates the signal change in one calculation step.
Discrete Derivative: Calculates the discrete time derivative.
Discrete Filter: Infinite impulse response (IIR) filter model.
Discrete FIR Filter: FIR filter model.
Discrete State-Space: Realises a discrete system in the state space.
Discrete-Time Integrator: Discrete integration or signal accumulation.
Discrete Transfer Fcn: Discrete transfer function.
Discrete Variable Time Delay: Delays the signal for a variable time value.
Discrete Zero-Pole: Simulates a discrete transfer function with specified poles and zeros.
Memory: Outputs the input values from the previous calculation step.
Propagation Delay: Simulates the time delay in a discrete system.
Tapped Delay: Delays a scalar signal for several calculation steps and outputs all delayed versions.
Unit Delay: Delays the signal by one calculation step.
Zero-Order Hold: Performs a zero-order hold during a calculation step.
