Time delayed recording system

摘要

A time delay apparatus has a multistate switch and a delay medium. The time delay apparatus is used in combination with a receiver/amplifier and a recording system. A continuous signal is switched from the receiver/amplifier to the delay medium when it is desired to store a selected portion of the continuous signal. By switching the continuous signal to the delay medium, a delay signal may be monitored so the decision to store the selected portion may be made ex post facto of its occurence. The delayed signal is then switched to the recording system to store the selected portion at the appropriate moment.
