pulse generator
Học thuậtThân thiện
Definition
Noun: A device or circuit that produces one or more electrical voltage pulses. It is typically designed to allow adjustment of the pulse repetition rate (how often the pulses occur).
Usage
A pulse generator is a piece of electronic test equipment used in laboratories, engineering, and medicine to create precise electrical signals for testing, stimulating, or synchronizing other devices.
Examples
- The engineer used a pulse generator to test the response time of the new circuit.
- In the experiment, the pulse generator was set to deliver ten pulses per second.
- The function of a cardiac pulse generator is to regulate the heartbeat.
Advanced Usage
- Adjustable Parameters: Beyond the pulse rate, advanced pulse generators often allow control over other parameters such as pulse width (duration), amplitude (voltage height), and shape (e.g., square, triangular).
- Applications: Used in digital logic testing, radar systems, laser drivers, and as the timing clock source in many electronic systems.
Variants and Related Words
- Signal Generator: A more general type of generator that can produce various waveforms (sine waves, square waves, etc.), not just pulses.
- Function Generator: Similar to a signal generator, often capable of producing pulses alongside other standard waveforms.
- Clock Generator: A specific type of pulse generator that produces a continuous, regular train of pulses to synchronize operations in a digital system.
Synonyms
- Pulse Source
- Pulse Producer
Related Phrases
- To generate a pulse: The action performed by the device.
- The circuit is designed to generate a pulse when the button is pressed.
- Pulse train: A series of pulses produced by the generator.
- The oscilloscope displayed a clean pulse train from the generator.
Noun
- a generator of single or multiple voltage pulses; usually adjustable for pulse rate
