The width of a pulse and power are related by a term called duty cycle. Full power means the pulse comes ON and Stays ON continuously for 100% duty cycle. No power means pulse is OFF continuously for a 0% duty cycle. 50% duty cycle means pulse stays ON half the time and OFF half the time. Duty cycle can be used to explain the relationship between pulse and power content.

How does the pulse width affects the function of the laser?
The pulse width of a laser influences its peak power and energy delivery. Shorter pulse widths result in higher peak power, which can enhance precision in applications like material processing or medical procedures. Conversely, longer pulse widths may lead to increased thermal effects, affecting the material being processed. Ultimately, the choice of pulse width depends on the desired outcome and application of the laser.
What is the use of IC 555 in generating pulse width modulation signal?
A pulse width modulated signal would be very useful in a switching power supply. This is but one example. Note, however, that there are better examples than the 555 for use in a switching power supply.
How do you calculate the width of pulse in pulse position modulation?
The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
What are the types of pulse modulation?
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
Smaller the pulse width larger is the bandwidth How?
For the Radar Case: The bandwidth of the pulse is the reciprocal of the Pulse Duration (called Pulse Width) as any filtering needs to be able to detection and follow the pulse shape and its edges. The pulse width is the AM modulation to a Fixed Frequency Carrier Frequency and the AM modulation will be greater bandwidth then the Carrier Frequency. As you are attempting to reject receiving other emissions and noise that do not match your own emissions such that your receiver is "match filtered" to your emissions, your receiver bandwidth will be at least the reciprocal of the pulse width but is lightly to be a smaller bandwidth then the reciprocal of the pulse width.
Application of pulse width modulation?
PWM finds use in power applications like dc motor speed control
What do you mean by pulse width modulation?
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
Is there a minimum pulse width required for the interrupt signal?
no
When you increase the width of a pulse?
increased rms value
How does pulse width affect wave speed?
In general, pulse width does not directly affect wave speed. The speed of a wave is determined by the medium through which it is propagating and the properties of that medium, rather than the pulse width itself. However, in practical applications, a shorter pulse width may allow for a higher data transmission rate in communication systems, which can indirectly impact the speed of information transfer.

Explain with diagram the technique Pulse-width modulation?
PWM explain with graphs?
Pulse Width Modulation (PWM) is a technique used to control the power delivered to electrical devices by varying the width of the pulses in a signal. In a typical PWM waveform, the x-axis represents time, while the y-axis represents voltage. The duty cycle, defined as the ratio of the pulse width to the total period, determines the average voltage and thus the power delivered; a higher duty cycle means more power. Graphically, a PWM signal appears as a series of square waves, where the width of the "on" state varies according to the desired output.
