The problem of high-fidelity reception is simplified to some extent because only local-station service is feasible due to the congested condition in the standard broadcast band. However, all of the general receiver problems are encountered in sets designed for both high-fidelity and weak-signal operation. A receiver suitable for both types of service is described here. In the design of a high-fidelity receiving system four sections of the system are of primary importance: 1. the loud speaker, 2. the audio amplifier, 3. the intermediate-frequency tuner and second detector, and 4. the radio-frequency tuner. Each of these sections is discussed and their relationship to high-quality performance is considered. Data applying to certain sections of the receiving system are presented and certain over-all data related to high-fidelity performance are included.
