Abstract

Method and means are disclosed for producing a D.C. signal proportional to the peak amplitude of an A.C. signal, which peak amplitude is proportional to the frequency of the A.C. signal. A second A.C. signal is generated from the first signal, having a frequency higher than that of the first signal and the second signal is rectified to produce an analog signal. The increase in frequency permits the subsequent processing of the analog signal in a high-frequency filter having a lower time-constant than would be possible were the analog signal produced directly by rectifying the first A.C. signal.
