 In the examples of digital circuits so far (i.e [adders](/Electronics_and_Hardware/Digital_circuits/Half_adder_and_full_adder.md) and [latches](/Electronics_and_Hardware/Digital_circuits/Latches.md)) everything happens in a single instant or over several repeated instances. This is because of how simple the circuits are. In the case of latches only a single bit is updated. And even with rippled adders they are just a series of 1-bit updaters in a chain.
 
-With more complex circuits that use multiple memory devices which store a series of bits at once, we need a way to ensure that the bits are set at the same time.

-We synchronize multiple circuit components with a **clock signal**.

-A clock signal alternates its voltage level from high to low on a regular cadence where it is high half the time and low the rest of the time. This gives the wave form a squared appearence.

 A single iteration of the volatage rising and falling is a **pulse**. A complete oscillation from low to high and back to low is a **cycle**. As with all [electromagnetic](/Electronics_and_Hardware/Physics_of_electricity/Electromagnetism.md) signals we measure the frequency of the wave in Hertz: cylcles per second. We also further distinguish the rising and falling edge of a pulse. Rising represents the signal passing from ground to its maximum voltage and falling is the reverse (the electrons moving from the voltage source to ground).
 
 The diagram below shows a pulse cycle of 2Hz.

+## Programable gates

+One of the main use cases of multiplexors is to implement programmable gates. These are gates where the logic can be switched. For example an ANDMUXOR gate uses the SEL value to toggle the operation of a gate between AND and OR for its two inputs A and B
