sonic delay line
A scientist uses a sonic delay line to measure the speed of sound in a liquid.
Noun: A sonic delay line is a type of delay line, an electronic component or circuit, that creates a time delay for a signal. It operates based on the principle of the finite time it takes for sound waves to travel through a physical medium, such as a liquid (e.g., mercury) or a solid (e.g., a quartz crystal). The electrical signal is first converted into an acoustic (sound) wave, which propagates through the medium, and is then converted back into an electrical signal after the delay.
This term is highly technical and is used primarily in the fields of electronics, computer engineering, and telecommunications history. It describes a specific method for creating a signal delay. - Example: "Early computer memory systems sometimes used a sonic delay line to temporarily store data bits."
- Historical Context: Sonic delay lines were a crucial technology in early digital computers, such as the UNIVAC I and EDSAC, where they functioned as a form of volatile memory (acoustic memory). The data, represented as sound pulses, would circulate in a medium, creating a delay that allowed it to be "stored" and retrieved.
- Delay line (n): The general category of devices for introducing a time delay into a signal transmission.
- Acoustic delay line (n): A synonym for sonic delay line.
- Mercury delay line (n): A specific, common type of sonic delay line that used a column of mercury as the propagation medium.
- Acoustic delay line
- Signal propagation delay: The general phenomenon of a time lag for any signal.
- Acoustic memory: The use of sonic delay lines for data storage in early computing.
