The repeated current in the plate circuitreferred to above is of radio frequency and is thereforenot heard in the telephone, the latter instrument indicatingonly the rectified current flowing from plate to repeated radio frequency current is utilized, however,in the regenerative and amplification circuits to bediscussed later. The terms audio-frequency component of the platecurrent and radio frequency component of the plate currentare given to the charge which accumulates in the gridcondenser during a group of incoming oscillations, and therepeated radio frequency current respectively.® To sum up the relaying and rectifying propertiesof the oscillation valve discussed above, it may be saidthat while the tube is acting as a detector (rectifier) itis also acting as an amplifier - that is, oscillations ofgreater power are produced in th
