Simulink: Convert Continuous Signal to Discrete
I am very new to simulink, so this question may seem simple. I am looking for a way to sample a continuous signal every X number of seconds.
essentially what I am doing is simulating the principle of a data acquisition unit for a demonstration I am running, but I can't seem to find a block to do this, the nearest thing I can get is the Zero-Order-Hold.
Answer
What you may need is a combination of two blocks. First, a Quantizer block to discretize the input to a chosen resolution. Second a Zero-Order Hold block to sample and hold at the chosen sampling rate.
The ordering doesn't seem to be of much importance here.
Here's an example:
