  • Abstract
    A square-law power-level recorder is described which is a new and improved version of a type of recorde which measures a-c voltage (or power level) on a linear decibel scale by means of a motor-balanced slide-wire attenuator.1 The detector, which is responsive to the mean square of the instantaneous voltage of its input, and the problems encountered in the insertion of this detector into the instrument, are described in detail. Other improvements in the circuit with the resulting improved performance are presented.
