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.

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.
