Circuits and methods for generating a bypass pulse to an RF circuit that increases the response time of the circuit to mode changes. Embodiments include a pulse generation circuit that it is self-initiated and self-terminated, generating a bypass pulse as a function of voltages V1 and V2 ...
CIRCUIT ARRANGEMENT FOR CONNECTING A PLURALITY OF FREQUENCY MULTIPLIER STAGES TO A COMMON FUNDAMENTAL FREQUENCY GENERATOR A circuit arrangement connects a plurality of frequency multiplier stages, each producing a different output frequency, and only one of which operates at a specific time, to a common...
aTo generate a digital circuit of PWM pulse fast development thus through special circuit or by programmable logic device PWM pulse generator has very convenient and see significant improvement in terms of speed and resolution and device with programmable function, so the control of active power ...
In order to improve the output waveform quality of electrical fast transient pulse / burst generator,the working principle of its main circuit is analyzed,the equivalent circuit of pulse train generator is established,the charge / discharge process of energy-storage capacitor in equivalent circuit is...
Switching the transient process (to cut off inductive load, relay contact bounce, etc) usually interferes with other electrical and electronic equipment in the same circuit. This type of interference is characterized by high amplitude, short rise time, high repetition rate and ...

Experimental confirmation of this has been achieved with a resistively charged 20 kV pulse generator (Cwas varied from 5 to 35 nF) switched by a spark gap into a load whose resistance varied from few ohms to a kΩ.关键词: Electrical resistivity Sparks Charge transfer Circuit theory Energy ...
The prediction of the effects of this test during the equipment early design stage requires the equivalent circuit of the generator: the output waveform into a resistive 50-Ω load is not sufficient to recover the complete circuit, including inductive component and parasitic elements. These are ...
In comparison, it is about ten times faster than the HP 811x series of pulse generators, but they are ancient (still expensive on eBay though!). The circuit was designed to use the parts that I had at hand, but it is easy to modify and select a different 74AC series logi...
The pulse generator has a pulse output voltage of 12 to 20,000 volts. There is also a circuit controller (16) having terminal voltage sensing means for a battery to be charged and a pulse controller for controlling the frequency and pulse duration characteristics of the pulse generator during ...
