Abstract
In the control of prime movers, automatic and manually generated input signals should be able to be entered into the control system without undue control disturbance or perturbation. Likewise should an automatic signal fail, the switch to a last valid signal prior to entry into a manual mode is also desirable. An analog-digital hybrid circuit is described which includes a memory, storage, timing and manual input portions as well as certain select A or B circuits which allow for bumpless transfer between automatic manual and memory modes of operation.
