Dear Damian,I want to simulate a TDM system as the project I uploaded.I have thought over my application maybe 1s time window is not necessary.my application is a time transfer via optical link system.The remote signal will be sent after 1 second.IF I want to set the time window 1 second ,i am so interested to the solution you said another way.By the way ,what is the difference between optical delay and time delay.
thankyou so much for spare your valuable time.
