What is meant by clock pulse in computer organisation?
Mahendrapasupuleti
the timing of all registers in the basic computer is controlled by a master clock generation.the clock pulses are applied to all flip-flops and registers in the system,including the flip-flops and registers in the control unit.the clock pulses donot change the state of register until it recieves an signal from control unit,these control signals are generated in control unit and provide control inputs for multiplexers in common bus to choose a particular process register!

∙ 12y agoA clock pulse is one cycle of the system clock. Some processors (such as the 8085) use that as their primary clock. Others, like the more advanced (current) Intel chips, internally multiply the clock to generate an internal clock at a higher speed.
Each instruction is executed in one or more clock pulses, depending on the instruction and on the processor. The minimum instruction time, for instance, for the 8085 is 4 clock cycles. The maximum, for some of the repeated string operations on an advanced processor, could be thousands.
Access to memory is also controlled by the external clock. In the 8085, 3 clock cycles are required to read or write one byte. In the advanced processors, 2 clock cycles can read or write 8 or even 16 bytes at a time.

How do you make electricity into the computer?
A computer operates by working with pulses of electrical energy. Depending on the voltage of the pulse, it represents either a zero or a one. Electricity is also need to spin the disc drives.
What is the proper tool to test a computer-controlled circuit?
Digital multimeters (DMMs) These tools are very good for measuring specific values such as voltage, amperage, resistance and pulse width
What is the Importance of leading edge and trailing edge in radar pulse?
The leading edge of a radar pulse determines range accuracy. The trailing edge, along with pulse width, determines minimum range.
What is the difference between pulse code modulation and delta modulation?
The difference between pulse code modulation and delta modulation is that pulse code modulation is a method of encoding audio information digitally while delta modulation is a method that converts analog to digital signal.
What is difference between pulse radar and CW radar?
CW or continuous-wave radar cannot determine range due to the lack of a listening period where the radar signal is silent. Pulse radar has a silent listening period (hence the name pulse radar). Therefore it can determine the range of the object causing the return by counting the elapsed time between transmission and receipt of the echo. The above is not quite correct, Continuous Wave Radar and Pulsed Radar differ by there relationship between the Pulse Width (tau) and the scene size (Swath). CW Radar's determine range by Frequency Modulation (FM) ranging this means that they ramp the RF frequency within the pulse during the transmission and are known as FMCW Radar. Pulsed Radar on the other hand use the pulse timing but can also use the FM Ranging trick to enhanced there signal to noise and reduce there probability of interference or detection/interception. CW radar can deduce range by delaying the transmit signal and mixing it with the receive such that it becomes a homodyne receiver and in such cases it is usual to ramp the RF and perhaps use two aerials rather then just one with a duplexer switch like in a Pulse radar system. Edit- hmm i feel the above answer is bit too complex... i don't think typical person would go as far as concerning FM or Pulse Delay Ranging here's my Answer DIFFERENCES BETWEEN PULSE AND CW RADAR Basis -Transmission Pulse RADAR puts delay between transmitting and receiving periods so the time between transmitted pulse and received pulse is different While CW RADAR, Transmit continuously -Antennas Pulse RADAR may use same antenna for Receiving and Transmitting , when transmitting the receiver is "blanked" and while Receiving the receiver is Activated and transmitter is blanked .. this is done by a device called "Duplexer" CW RADAR typically used 2 Antennas, one for transmit another one to Receive since there are no delay to receive as what usually seen in pulse RADAR -Ranging technique Pulse RADAR may use "Pulse Delay Ranging" to provide Range measurements , Frequency Modulation Ranging may also possible , especially for pulse RADAR that transmit many pulses and have very shot time to "listen" example is FMICW (Frequency Modulated Interrupted Continuous Wave RADAR) While CW RADAR provides Range by means of Doppler based Ranging (FM Ranging)
Why a clock is necessary for a microprocessor?
Microprocessor processes something on each clock pulse
What is a pulse rate of a clock measured in?
frequency of an oscillator crystal
Differecne between synchronous circuit and a asynchronous circuit?
Synchronous circuits operate under the influence of s clock pulse while asynchronous circuits operate without the influence of a clock pulse
What no of instruction will be execute by using only one clock pulse in 8085 microprocessor?
There are no instructions in the 8085 that execute in only one clock pulse. The minimum number of clock cycles is four; three for instruction fetch and one for instruction decode/execute.
How is a pulse described as regular or irregular?
If you think of an old clock that ticks, it has a regular rhythm. Pulse can be regular like a clock.. tick...tick...tick... An irregular pulse has shorter or longer pauses between beats...ticktick...tick.......tick...tick...ticktick...
What are clock inputs?
A clock input is a regular periodic pulse that can be used as a trigger to sequence timing-important activities.
Is clock pulse an ac or DC signal?
It is called ( pulsed DC ).
How did Galileo measure the timing of the balls with no clock?
probably counted his pulse
Does this treadmill offer a pulse checker and calories burned clock?
Yes, this Ironman Acclaim Treadmill does display the number of calories you have burned.
What is a t flip flop?
toggle: at every clock pulse it switches state.
Why 2 grounds are used in microprocessor?
one is for the vcc and another for the clock pulse
Explain why the clock pulse must be very narrow?
So it can be precise for measuring time.
