noun
superheterodyne receiver
Technical term in radio engineering; refers to a receiver that converts a high-frequency signal to a lower intermediate frequency for processing.
スーパー受信機は、ラジオやテレビの受信回路で広く使われている。
Superheterodyne receivers are widely used in radio and television reception circuits.
From English 'superheterodyne' + 受信機 (receiver). The prefix スーパー is a clipping of 'superheterodyne', not the general 'super'.
