AM radio receivers require a high quality factor (Q) to achieve sharp resonance and minimize interference between closely spaced frequencies. The relationship between Q, frequency, and frequency separation is crucial, as a higher Q indicates a narrower bandwidth, allowing better reception of desired signals. For effective AM reception, the Q factor must be sufficient to prevent overlapping signals from different stations, which typically operate with a 10 kHz separation. While specific Q values for good reception are not universally defined, they can be estimated based on the required frequency difference. Understanding these principles is essential for optimizing AM radio performance.
