Période

THIS TYPE OF RECEIVER USED 1927+

Canada

THIS TYPE OF RECEIVER MFD IN HAMILTON, ON BY CANADIAN WESTINGHOUSE CO. LTD. IN 1927.

Fonction

TO DETECT AND AMPLIFY RADIO SIGNALS.

Technique

TUNED RADIO FREQUENCY (TRF) RECEIVERS USE ONE OR MORE STAGES OF RADIO FREQUENCY AMPLIFICATION BEFORE A SEPARATE DETECTOR STAGE: EACH STAGE HAS TO BE SEPARATELY TUNED. THOUGH REQUIRING MULTIPLE TUNING CONTROLS AND A RELATIVELY LARGENUMBER OF EXPENSIVE VACUUM TUBES, TRFS WERE MORE SELECTIVE, MORE SENSITIVE & LOUDER THAN COMPETING REGENERATIVE RECEIVERS. (REF. 1)
