Question

Clock circuits are used to pace the activity of many systems, where at the leading and trailing edge of every clock cycle some activity is caused to occur. Consider for example, an I3 microprocessor, having a clock speed of 3 GHz. This means that within the integrated circuit of the microprocessor there is a pulse train generator with a 0.333 x 10-9 second cycle time. Therefore, within the time span of 1/3 of a nano-second the microprocessor executes some activity. However, an LM555 cannot produce a clock signal at this high a frequency, and therefore the clock generator within such a microprocessor is made with other electronic devices that can switch at such high speeds. Give an example of another device or system, which you use regularly, that has within it an electronic clock that makes the device work the way it does. For your example, explain the purpose of the electronic clock.

Explanation / Answer

we are regularly using personal computers, video camera , video games and celluar phones which is having internal electronics clock to generate the internal clock signal so that particular device works properly. Here in this all systems clock signal is used to provide the synchronized pulse between the different activity. clocks controles the timing in the circuit. it controls all of the logic and arithmetic operations. but the fact is this will affect the the speed of a computer because the gates need to wait for the clock to change from low state to high state or vice versa. If we are not using lcock signal here then gates will change whenever we provide any command so to provide the effcient results need to use clock signal in side the devices.
