Abstract
1,104,668. Recording and playback. MICROWAVE INSTRUMENTS Ltd., and J. BILBROUGH. 22 June, 1966 [25 June, 1965], No. 27150/65. Heading G5R. Weak repetitive signals (e.g. from an electron spin resonance spectrometer) are separated from random electrical noise by repeatedly recording the signals and noise together on an endless magnetic track (e.g. on a rotating drum, disc, or annulus) which is displaced in synchronism with the repetition frequency of the signals and partially erasing the record prior to each repetition of the recording cycle. The repetitive signals are always recorded on the same portion of the track, whereas the random noise signals tend to cancel each other out. An insert of magnetically susceptible material or a small permanent magnet may be incorporated in the track to provide a reference signal for controlling synchronism between the displacement of the track and the repetition of the signals.
