This block is similar to the Sample block. The only difference is that after the sampling of the input signal, simulated real-world effects are applied on the sampled signal. In particular:

• The output is limited, if parameter limited = true.
• The output is value discretized in the form of an Analog-Digital converter with a definable number of bits, if parameters limited = true, and quantized = true.
• Noise is added to the output if parameter noisy = true. A pseudo random number generator is used to generate uniformly distributed random numbers in a given band.

Example

The following example samples a sine signal with a periodic clock of 20 ms period, and adds the following effects:

• Limits the output to +/- 0.8.
• Discretizes the output with an 8 bit AD converter.
• Adds large uniform noise with a band of +/- 0.2.

	model	simulation result

The output y is quite far away from the continuous-time input signal, due to the strong discretization and large noise applied to the sampled input.

noisy	Value: false Type: Boolean Description: = true, if output should be superimposed with noise
limited	Value: false Type: Boolean Description: = true, if output is limited
quantized	Value: false Type: Boolean Description: = true, if output quantization effects included
yMax	Value: 1 Type: Real Description: Upper limit of output (if limited = true)
yMin	Value: -yMax Type: Real Description: Lower limit of output (if limited = true)
bits	Value: 8 Type: Integer Description: Number of bits of quantization (if quantized = true)
