The Beijing researchers then extended the bouncing startup investigation in , 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
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.
In NRZ, the binary 1 and 0 are a positive and a negative square wave
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.
