Delay is frustrating, whether in our daily lives or the devices we use for our convenience. Propagation delay/time delay inhibits the intended functions of the devices. When I say ‘devices,’ I am trying to draw your attention towards the components responsible for a product’s basic functionality. These components are arranged in a specific manner based on a circuit etched on a PCB.
