20.6.6.10. Quantizer
The Quantizer block discretizes the input signal at specified interval.
The system is defined by
\(y=q \times round \left( \frac{u}{q} \right)\)
- where,
- \(y\) is the output signal\(u\) is the input signal\(q\) is the quantization interval specified in the block parameter.

20.6.6.10.1. Example
We can test the Quantizer block with the CoLink model shown in the below figure The Sine block is configured to a frequency of 1rad/sec and an amplitude of 1. The Quantizer block Quantization Interval is set to 1. Set solver type to Fixed-Step, discrete (no continuous states), and let End time be 1
