Transport delay - short pulse, long delay

Hello,

I would like to delay digital signals. For delaying signals I found the "transport delay" block.

Unfortunately it doesn't show the wanted behaviour.

My use case: Long term delay (some µs) of short pulses (ns).

Scope output:

Due to the ratios of pulse, delay and step size the pulses seem to be absorbed somehow.

The parameters:

Pulse generator: 1ns pulse each 5µs

Transport delay: 1µs delay, buffer size: 1024

Solver: Variable step, discrete, max step size (I would like to keep those)

How can I achieve such delays in Simulink?

Thanks a lot and best regards

Tom

you don't need a transport delay block. Just set the phase parameter of your pulse generator block to 10^(-6)

If you want to use a delay block, you need to change the step-size to fixed with for example step=10^(-10)

Hello Azzi,

Thanks for your answer. Sorry, the picture above was just an example for visualizing the effect.

I would like to delay any digital signal.

Please imagine it like this:
