THREE SONIC DELAY LINES FOR A VLF SYSTEM
Abstract
The design, construction, and operating characteristics of 3 sonic delay lines are described. The lines were built by the Naval Ordnance Laboratory Corona to produce the delay of electrical signals within the frequency range of 1 to 30 kc. Two delay lines (25-ms and 65-ms), designed for 1.3-kc signals, functioned satisfactorily; a 0.5- to 5-ms delay line for 10- to 30-kc signals was unsatisfactory because of relatively strong spurious signals. The conclusion is reached that for the higher-frequency application a sonic delay line based on a different principle would be more suitable. (Author)
