A signal used to synchronize the operations of an electronic system. Clock pulses are continuous, precisely spaced changes in voltage.
What is the use of clock pulse in flip flops?
A clock pulse is a time varying voltage signal applied to control the operation (triggering) of a flip flop. For example, if a clock pulse is of frequency 1 Hz, the voltage it will supply will oscillate between X Volts and Y Volts(X and Y are any dc voltages), and this change occurs every half second.
What is the purpose of using a clock signal in a microprocessor?
The clock signal is the timing signal used in all CPUs . If you don’t have a clock signal the cpu will just sit there because it has nothing at all to tell it when to do things. if anything happened at all it would be every instruction trying to execute at the same time not a good situation.
What is difference between pulse and clock?
Your microcontroller may have a 16 MHz clock, then the clock generates 16 million pulses per second. So a clock signal consists of an indefinite series of pulses. A pulse is sudden change in signal level, in a digital signal from low to high or vice versa, and after some time a return to the original level.
What is a clock a pulse a trigger?
The output of a flip flop can be changed by bring a small change in the input signal. This small change can be brought with the help of a clock pulse or commonly known as a trigger pulse. When such a trigger pulse is applied to the input, the output changes and thus the flip flop is said to be triggered.
Do you think clock pulse and pulse train are same Justify your answer?
They are cousins sharing the same DNA -hence the resemblance and your confusion. A pulse train can be trimmed to act like a clock signal and vice verse.
What is clock pulse in microcontroller?
The CPU, the memory bus, the peripherals—clock signals are everywhere inside a microcontroller. They govern the speed at which the processor executes instructions, the baud rate of serial-communication signals, the amount of time needed to perform an analog-to-digital conversion, and so much more.
What is clock cycle?
A clock cycle is a single period of an oscillating clock signal. Clock speed, rate, and frequency are used to describe the same thing: the number of clock cycles per second, measured in Hertz (Hz).
What is positive and negative edge triggered clock?
When there is a transition from 0 to 1 it is named as positive edge triggered and when the clock pulse makes a transition from high to low i.e. from 1 to 0 it is termed as negative edge triggered.
What are the features of clock pulse?
Clock pulses are continuous, precisely spaced changes in voltage. See clock speed.
How do you stop clock pulse?
Make sure you gate it so that going to the off state does not trigger an additional count. I.e. use a NOR gate to do the gating of the clock to the counter; using a positive logic equals signal will force the NOR output low when equal so make sure the counter does not advance when the input goes low.
