DC motors use PWM (pulse width modulation), which can easily increase or decrease the power to the motor, thereby increasing or decreasing the motor speed by modulating the width of the pulse. Stepper motors have fixed frequencies, thereby having fixed motor speeds. As a result, the speed of the stepper motor cannot be controlled when the load is increased.
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.

i'm not really sure, but if i'm not mistaken, you should know the frequency of the PWM and it's duty cycle. For an example, if f = 10khz & duty cycle = 90%. f=1/t, so t=100microsecond, 90/100 x 100microsecond = 90microsecond. So the width of PWM is 90microsecond

The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
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.
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)

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?
Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
Mark of space ratio. M/S=pulse width/space width.
When the pulse width to an injection control pressure regulator (ICPR) is increased, it generally results in a longer duration of fuel injection. This leads to an increase in the amount of fuel delivered to the engine, which can enhance power output and performance. However, if the pulse width is excessively increased, it may also lead to fuel enrichment and potential engine inefficiency or misfire. Proper adjustments are crucial to balance performance and emissions.
