rectangular pulse

rectangular pulse

[rek′taŋ·gyə·lər ′pəls]
(electronics)
A pulse in which the wave amplitude suddenly changes from zero to another value at which it remains constant for a short period of time, and then suddenly changes back to zero.

For example, PET-7 generates a pulse with a gain of 1 [micro]s and a duration of 256 [micro]s or ZED-meter--a rectangular pulse duration 1.4 [micro]s.
The system contains an excitation channel, which is able to generate either single rectangular pulse or more complex rectangular waveform.
At a similar strain rate, the specimen under rectangular pulse absorbed more energy compared with that under the half-sine stress pulse.
Consider that a 0.95 ns rectangular pulse centered at 10 GHz is incident on a 20-element linear array with a 25 dB Taylor taper.

A single rectangular pulse of 1 m/s over a period of 2 ms (Reynolds number = 4000) as shown in Figure 3 was applied at the tube inlet to serve as the driving force to produce a propagating wave.
Where [DELTA] defines the shift of rectangular pulse center from the start of revolution.
If we limit the interest case to single rectangular pulse, one can obtain a detection effect by actually detecting the sharp pulse edges or by spectral decomposition of the pulse itself, when the edges have relatively slow rise and fall times.
Assuming the system was excited by rectangular pulse, the three-dimensional shock spectrum and the damage boundary surface were obtained by Wang and Chen [24-26].
