Abstract
A control method and apparatus for dual slope analog to digital signal conversion is disclosed in which the time required for input signal integration is sensed. A switch connected across the integrator is closed in response to sensing of an integration time which exceeds the integration interval corresponding to a limit of the expected range of input signal values.
