Description
Summary:A continuous dual sensitive meter system is described in this report which is capable of replacing two meters previously used in the AN/BRA-27 control system. This system retains the basic desirable qualities of both the previous meters, i.e., accuracy in the 0-50 foot region, and ability to track continuously to maximum cable length. In the development of the system, a simple transistor circuit is shown to give the desired characteristics. A circuit using Op amps is also shown. Performance data for both circuits are given.
