7 1-44.   Power in an audio-frequency circuit is stated in which of the following units? 1.   Decibels (dB) only 2.   Decibels referenced to 1 milliwatt (dBm) only 3.   Both dB and dBm 4.   Volt units (Vu) 1-45.    The bel is a unit of measurement used with voltage, current, or power that compares which of the following circuit values? 1.   The input to the output 2.   The output to a reference 3.   The voltage to power 4.   The current to power 1-46.   What is the relationship between the values of the bel and the decibel? 1.   The bel is twice the decibel 2.   The decibel is twice the bel 3.   The bel is 1/10 the decibel 4.   The decibel is 1/10 the bel 1-47.   What is the corresponding increase in dBm each time power is doubled? 1.     +1 dB 2.     +2 dB 3.     +3 dB 4.   +10 dB 1-48.   A thermocouple ammeter is used to measure which of the following quantities? 1.   Rf current 2.   Af current 3.   Motor current 4.   Generator current 1-49.   A bolometer is a power meter that measures power in certain frequency ranges. Which of the following methods is/are used by the bolometer to measure power values? 1.   A barretter detects increases in power when its resistance increases 2.   A thermistor detects increases in power when its resistance decreases 3.   Both 1 and 2 above 4.   Power is measured directly THIS SPACE LEFT BLANK INTENTIONALLY.
