Analog Delay Lines
Peculiar Parts, the series
It isn’t always necessary to add a propagation delay to a signal but sometimes it’s the only way to make a circuit operate properly. A classic example is the trigger circuitry in an analog oscilloscope. The circuit can typically take 60 ns to detect a trigger event so any signal sent to the CRT must be delayed by the same amount to can be displayed correctly.
