Hello,

could you please describe me the difference between buffer and zero-order-hold? I configured a rate transition in an example (see image) to act in both ways. But I can't see any difference.

Best regards

Hi,

There is a slight difference between ZOH and Buf. The ZOH ensures the maximum capacity and maximum "data integrity" during data transfer. While "Buf" only ensures "data integrity" during data transfer. This difference would be noticeable when having blocks with huge difference in data rates, when Buf wont be able to store input.
