Examples.AccumulatorDemo

Test harness that samples a sine wave and accumulates it using both accumulator types.

This model demonstrates:

• Generating a continuous sine wave
• Sampling it at a fixed rate (10 Hz)
• Accumulating the discrete samples using both syntactic and graphical approaches

Usage

DiscreteComponents.Examples.AccumulatorDemo()

Parameters:
