An electronic instrument with digital readout has been designed and constructed for indirect determination of the kVp applied to diagnostic x‐ray tubes. The signals from two detectors exposed simultaneously to a differentially filtered x‐ray beam are processed by analog computing circuitry to yield an output signal directly proportional to the applied peak kilovoltage. Theory and preliminary results are presented and discussed.
