Abstract

The limiting sensitivity of an alternating-current system of amplification is considered. The practical limit is determined theoretically and experimentally for measured circuit parameters. A particular circuit using an electrometer-tube and a cesium-antimony cell is shown to be capable of detecting 4.5×10<sup>−15</sup> watt in 30 seconds. Data on various input-tubes and photoelectric cells are given.
