  • Abstract
    Frequently in measuring physiological variables it is necessary to store an electrical signal for relatively long periods of time. The circuit presented has been designed for this purpose, and can operate with signals up to±10 v with drift rates dependent upon the stored voltage but typically less than 7 mv/hr.
