Q

In a microprocessor-controlled two-way radio, a “watchdog” timer:

🔍 Key Concepts

• Role of a watchdog timer in digital/microprocessor systems • What happens if a microprocessor stops or locks up • Which choices relate to frequency/power control versus program execution

💭 Think About

• Ask yourself: in general electronics (not just radios), what is a watchdog timer used to detect or correct? • Which answer choice describes something that specifically involves monitoring the microprocessor’s operation, rather than the RF signal or external equipment? • Eliminate the options that deal mainly with radio frequency, power output, or external displays—does a timer usually handle those?

✅ Before You Answer

• Identify which option talks about the microprocessor’s program operation itself. • Check which options instead deal with RF frequency accuracy or power limits—these are usually handled by other circuits, not a watchdog timer. • Confirm that the best choice describes a function that would be needed if the microprocessor crashes or stops running correctly.
