A control pulse generator for the cyclical fault-free generation of an accurate sequence of control pulses utilizing a quartz pulse generator which is operatively connected to and adapted to initiate actuation of a plurality of serially connected to delay members over a control circuit which is ...
It can generate single or dual pulses of either positive or negative polarity as well as alternating positive and negative pulses. The output amplitude is adjustable from 0Volts to + and – 10V peak. It operates in either free-running mode, triggered or gated mode. For more detailed ...
Acceleration pulses caused by heel strike, acceleration from leg swing, and thecompressive forceacting upon the shoe due to the weight of a person are the three energy sources from walking activity that can be harvested to generate electrical power. In order to harvest energy from these three di...
to limit the initiation of a succeeding cycle by a pulse from the generator to a predetermined period of time following termination of the first cycle of operation and functioning as a self-holding circuit when the period duration of the quartz generator signals coincide with the running time of...
The synthesized microwave pulses are sent to the qubit sample through coaxial cables with proper attenuation and filtering to suppress possible noises. When measuring with the cryogenic microwave source, the output of the signal source is directed to the transmon qubit sample. To determine the qubit...

Pulse Generator: When you need pulses of any sort, long, short and with variable frequency you can use one or two 555 timers. That works, is easy to set up and is cheap. But it also limited to a certain range in frequency and pulse length. If you want a

This oscilloscope screenshot shows the waveforms when running the hardware test program. The timer keeps it output high for 0.25 seconds following any rising edge trigger. The test gives 3 pulses, then waits. The waveform after this 3rd pulse tests a failure where Teensy might crash or lock up...
gate controlled switch or replaced by a complementary pair of transistors. With electronic switch 46 open, the circuit is free-running, producing pulses at a frequency determined by variable resistor 12. If switch 14 is closed, the circuit becomes monostable, and produces a pulse at 20 or 40 ...
