Finding the time delay between subsystems with different sample rates.

Hello all,

I have the following question:

I am considering two subsystems (a plant and a controller). These subsystems are considered as atomic units and operate at different sampling rates, 100kHz and 10kHz respectively.

How could I find the (processing) time delay of the signal sent from one subsystem (the one with higher sampling freq) to the other one (the one with lower sampling freqeuncy) ?

Thank you very much in advance.

From my understanding of the question, you want to find the time elapsed between the signal sent by the 100kHz and received by 10kHz sub-system. You can try looking into the Find Delay block present in the Simulink Library. The block can also accept a matrix input and output the delay in each channel independently.
