Pulse width is an important measure in radar systems. Radars transmit pulses of radio frequency energy out of an antenna and then listen for their reflection off of target objects. The amount of energy that is returned to the radar receiver is a function of the peak energy of the pulse, the pulse width, and the pulse repetition frequency.
After the calibration pulse, each nibble is transmitted with a fixed-width low signal, followed by a variable-length high period. The low pulse-width is 5 (or more) ticks in length, while the high pulse-width can vary, for a total period between falling edges of between 12-27 ticks (representing nibbles ranging from 0-15).

Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an electrical signal.
This technique is known as pulse-width modulation. In the printer / copier industry, the duty cycle specification refers to the rated throughput (that is, printed pages) of a device per month. In a welding power supply , the maximum duty cycle is defined as the percentage of time in a 10-minute period that it can be operated continuously before ...
The unit interval is the minimum time interval between condition changes of a data transmission signal, also known as the pulse time or symbol duration time.A unit interval (UI) is the time taken in a data stream by each subsequent pulse (or symbol).
In telecommunications and electronics, baud (/ b ɔː d /; symbol: Bd) is a common unit of measurement of symbol rate, which is one of the components that determine the speed of communication over a data channel. It is the unit for symbol rate or modulation rate in symbols per second or pulses per second.
Simple bench pulse generators usually allow control of the pulse repetition rate , pulse width, delay with respect to an internal or external trigger and the high- and low-voltage levels of the pulses. More sophisticated pulse generators may allow control over the rise time and fall time of the pulses. Pulse generators are available for ...
