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.
This output signal can be an analog voltage, a pulse-width modulation (PWM) signal, or be communicated digitally over a modern bus protocol. [6] Hall sensors may also be ratiometric if their sensitivity is also proportional to their supply voltage. With no magnetic field applied, their quiescent output voltage is typically half of the supply ...
The recommended operating environment is a temperature of 40 to 110 °F (4 to 43 °C), a relative humidity of between 2 and 95 percent, and an altitude of 0 to 10,000 feet (0 to 3,048 m). The printing paper is an 8.44-by-4.5-inch (214 by 114 mm) diameter roll, and the paper tape is a 1,000-foot (300 m) roll of 1-inch (25 mm) wide tape.
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 ...
Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was ...
The IBM 1132 was the last printer manufactured by IBM to use this technology. IBM 1403 printer opened up as it would be to change paper. The print chain is behind the wide black ribbon, hinged open to the right, which is the width of the paper. Also note carriage control tape in upper right.

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]
