square wave

[′skwer ′wāv]
(electricity)
An oscillation the amplitude of which shows periodic discontinuities between two values, remaining constant between jumps.

square wave

A waveform that rises quickly to a particular amplitude, remains constant for a time period and drops fast at the end. In digital systems, square waves are the norm, because they represent a binary digit (0 or 1). Square waves can also be generated in musical synthesizers and have a raspy sound.


Square Waves
This is the output of a 1 kHz square wave on an oscilloscope. Only the tops and bottoms of the waves are displayed, because the rising and falling is faster than the scope is set for.

The Beijing researchers then extended the bouncing startup investigation in [9], where a constant starting force, which changed sign with velocity, was employed to achieve a pulse width modulated square wave. For a 3kg translator mass with bore of 50mm, they simulated and achieved a compression ratio of ~20 and frequency of ~21 Hz with a forcing amplitude of 55 N.
A DDS (direct digital synthesizer) module AD9850 controlled by a MCU (microcontroller unit) controller is adopted to generate the accurate square wave exciting signal.
For the first time, the FinFET-based 6T SRAM internal nodes behavior is examined by using an array of square wave input of various RC delays and the minimum RC of a functional SRAM cell is acquired.
The ratio of on time to cycle time (duty ratio) of the square wave determines the amplitude of the output voltage, and hence can be varied to regulate voltage.
It has the ability to drive heavy loads and to replicate even square waves because of its high slew rate.
* Digital pins can generate the out-of-band signals, but digital pins only can generate square waves.
The sensor consists of an LED light source, photodetector IC, interpolator IC and line driver, with outputs consisting of two square waves in quadrature and a gated index pulse.
Triangle waveforms, ramp waveforms, and multilevel square waves also can be generated, subject to some limitations in the maximum useable frequencies.
These oscillators deliver two output signal formats: clipped sine at 0.8 V and HCMOS square waves with 40/60 waveform symmetry Aging at 25[degrees]C is
An autoset function offers automatic detection and a choice of different views of sine waves, square waves and video signals, including rising and falling edges, video lines and fields and FFT.
The seven models that comprise the TDS1000 and TDS2000 Series Digital Storage Oscilloscopes share several standard features: an FFT function to analyze, characterize, and troubleshoot circuits; triggering such as pulse-width, line-selectable video, and external; an autoset function for automatic detection with a choice of views of sine or square waves and video signals; display of four automatic measurements; and a probe check wizard.
