In a radio application we are reducing the AM or FM signal which is centered on the carrier frequency to some intermediate. Circuit diagram of a 7-tube automobile radio receiver, Philco Lincoln-Zephyr L-1424. When it is switched on, the oscillation phase is preceded by a short period of very high sensitivity. 2 synonyms for superheterodyne receiver: heterodyne receiver, superhet.
