🔍 Key Concepts

• Auto alarm receiver operation and purpose on 500 kHz distress frequency • Typical tuning tolerance around a designated distress frequency • Why a receiver must cover a band of frequencies instead of only the exact center frequency

💭 Think About

• Which option keeps 500 kHz as the center frequency with an equal range above and below? • Look at the difference between 500 kHz and each of the band limits in every answer — which one matches the stated "+/- 12.5 kHz" requirement? • Compare the total width of the frequency band in each choice and ask: which one is exactly 25 kHz wide and centered on 500 kHz?

✅ Before You Answer

• Confirm that 500 kHz is the center (tuned) frequency, not one of the edges. • Check that both upper and lower limits are exactly 12.5 kHz away from 500 kHz. • Verify that the resulting band is symmetric around 500 kHz and the total spread is 25 kHz.
