When I was doing scientific research--measuring correlations among nuclear events (specifically, the emission and detection of two gamma rays)--we needed delays to allow one signal to catch up to another, but it had to be very precise. Rather than using an electronic delay, we used hundreds of meters of coaxial cable, for precisely this reason. Even with sophisticated laboratory equipment, reflections due to impedance mismatch could complicate fast, sensitive measurements.
