An (ADL) is a specialized physical device that uses sound waves to introduce a precise time lag into a signal . By converting electrical signals into slower-traveling mechanical vibrations, these devices can "store" or delay information in a much smaller physical space than would be required by electrical transmission lines. Core Mechanism and Components
At the other end, a second transducer senses the mechanical vibration and converts it back into an electrical signal. Historical and Modern Applications acoustic delay line
An electrical signal is converted into an acoustic wave (vibration) using a transducer, often piezoelectric. An (ADL) is a specialized physical device that
