superheterodyne receiver in a sentence

Examples

1. Crystal-controlled superheterodyne receivers with better selectivity and stability made control equipment more capable and at lower cost.
2. Modern radio tuners use a superheterodyne receiver with tuning selected by adjustment of the frequency of a local oscillator.

4. The TR-1 was a superheterodyne receiver made with four n-p-n transistors and one diode.
5. Most superheterodyne receivers designed for broadcast FM ( 88-108 MHz ) use an IF of 10.7 MHz.
