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.
A code wheel is a type of copy protection used on older computer games, often those published in the late 1980s and early 1990s.It evolved from the original "manual protection" system in which the program would require the user to enter a specific word from the manual before the game would start up or continue beyond a certain point.
A game backup device, informally called a copier, is a device for backing up ROM data from a video game cartridge to a computer file called a ROM image and playing them back on the official hardware. Recently flash cartridges , especially on the Game Boy Advance and Nintendo DS platforms, only support the latter function; they cannot be used ...
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 ...
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.
Examples of pulse shapes: (a) rectangular pulse, (b) cosine squared (raised cosine) pulse, (c) Dirac pulse, (d) sinc pulse, (e) Gaussian pulse. A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. [1]

A new class of microwave pulse generation architecture, the RACE (Rapid Automatic Cascode Exchange) pulse generation circuit [1] [2] is implemented using low-cost monolithic IC technology and can produce pulses as short as 1 picosecond and repetition rates exceeding 30 billion pulses per second. These pulsers are typically used in military ...
