The paper describes a general-purpose facility for pulsed ultrasonic measurements. Basic characteristics of the facility are given. A circuit diagram of a synchronization unit is discussed.doi:10.1007/BF00862558A. G. OvchinnikovKluwer Academic Publishers-Plenum PublishersMeasurement Techniques...
Current drawing when in Pulse-Generator mode is about 60µA & 1.2mA when in Signal-Tracer mode operation. Therefore SW1 can be omitted, provided that the earclip or headphones are unplugged when the circuit is unused. J1 is a stereo switched jack socket wired to obtain a series connec...
The conventional method of generating a PWM modulated wave is to compare the message signal with a ramp waveform using a comparator. The block diagram required for the generation of a simple PWM is shown in the following: 1)Variable frequency sine wave generator A sine wave generator circuit is...

A pulse sequence generator for the production of pulse sequences whose pulse count depends on a geometrical value, such as a distance or an angle, comprises a first pulse generator which generates a s
Impermissible static FALSE signal at the IN input (closed-circuit current principle): If no further measures for exception avoidance are taken, a static FALSE signal at the IN input will cause the pulse generator to be idle continuously and it will not be possible to start it. ...
The generator mainly consists of a three-step resonant charging circuit switched by thyristors, a transmission line transformer, and a triggered spark-gap switch. Voltage pulses of 30–100 kV with a rise time of about 20 ns, a pulse duration of 50–250 ns, pulse repetition rate of 1–900...
The pulsed latch requires pulse generators that generate pulse clock waveforms with a source clock. The pulse width is chosen such that it facilitates the transition. The following diagram represents a simple pulse generator and the associated pulse waveform. ...
and down the street while I worked on my circuit in the back seat, I needed something to simulate pulses on the workbench. I got through the speedometer project with a 555 timer and a trimpot to simulate the driveline pulses, but my very next project was a general-purpose pulse generator...
A data latch circuit and a pulse signal generator thereof are provided. The pulse signal generator includes a first buffer, a second buffer, a pull-up switch and an output buffer. T
