  • Patent number: 4073194
    Abstract: A system for the periodic sampling and recording of a condition, such as noise. The system employs a transducer which gates strings of pulses to a tape recorder. The gating time is in accordance with the transducer output voltage at sampling time. At each sampling, a delay in recording is provided to allow the recorder motor to come up to speed. The recorded tape may be played back and the grouped recorded pulses counted and presented as noise levels which can be plotted against time.
