Abstract
Abstract A device is disclosed for recording high frequency signals on a lower frequency recorder. In accomplishing this, the high frequency signals are amplified and periodically stored in maximum and minimum storage devices. The stored maximum and minimum values of the high frequency signal are then sequentially applied through read amplifying circuitry to the lower frequency recorder which displays the signal retaining the amplitude thereof.
