Use

Domains: Discrete, Continuous. Size: 1-D. Allowed in: Block Diagrams.

Description

This model incorporates the basic functions of a digital to analog convertor: zero order hold, output window (i.e. restriction of the output between a minimum and maximum value) and quantization. The quantization is specified in bits. For example 8 bits quantization means the output has 2^8 - 1 = 255 possible values between the given minimum and maximum.

Limitations

The input of this model is a discrete signal. The output of this model is a continuous signal. 20-sim will automatically detect the existence of discrete models. Each chain of discrete models will be assigned a specific sampletime. You can set this sample time to any desired value in the Simulator (choose Properties, Simulation and Discrete System).
