The duration of light pulses (also called pulse width or pulse length) can vary in a huge range: By modulating a continuous-wave light source, e.g., with an electro-optic modulator, pulses with durations from some tens of picoseconds to arbitrarily high values can be generated. Gain switchi...
Advantageously with this approach, the ‘sweep-duration’ can be chosen independently from the bandwidth, the signal can simply be generated by means of a voltagecontrolled oscillator (VCO), and the spectral purity of the signal is very high. The latter enables easily to avoid non-intended emiss...
The pulse duration decisive means which decide the widthPROBLEM TO BE SOLVED: To provide a power converter which can reduce a high-frequency sound, is small in current variation, reduced in torque ripple, and low in vibration noise, and to provide a heat pump apparatus.松井 敬三...
Setting an ALS Pulse Interval and Width for a Laser Context The ALS pulse interval indicates the time between two consecutive pulses and applies only to the automatic restart mode. The ALS pulse width indicates the pulse duration and applies to both the automatic and manual restart modes. In au...
As the full power is only applied for 50% of the total duration, the power to the motor is 50%. OK I think maybe you can see where this is heading now! Waveform 3:This time the off time 'a' is 25% and the on pulse is 75% consequently 75% power is applied to the motor. ...

Pulse-width modulation (PWM) is a modulation process or technique used in most communication systems for encoding the amplitude of a signal right into a pulse width or duration of another signal, usually a carrier signal, for transmission. Although PWM is also used in communications, its main ...
Use the DAQmx Timing VI to configure the duration of the pulse generation. Note: The Implicit instance should be used when no sample timing is needed, such as in counter tasks like pulse train generation. Additionally, choose Continuous as the sample mode. Call the DAQmx Start VI; this VI ...
