1. Which FCC rule part primarily governs the technical standards and
station operations for broadcast radio and television services?
A. Part 15
B. Part 73
C. Part 90
D. Part 101
The FCC’s Part 73 contains the technical and operational rules specific
to broadcast radio and television services.
2. What is the minimum horizontal plane height above average terrain
used to determine the FM station’s protected contour?
A. 10 meters
B. 20 meters
C. 30 meters
D. 50 meters
For FM contours, average terrain is measured using the antenna
height above average terrain (HAAT) calculated with a 30-meter
reference baseline.
3. In broadcast engineering, what parameter does ERP represent?
A. Estimated Radiation Power
B. Effective Radiated Power
C. Electromagnetic Resonance Potential
, D. Extra Radiated Pressure
ERP is the product of transmitter power output, transmission line
loss, and antenna gain referenced to a dipole.
4. Which device is used to combine multiple transmitters into a single
antenna system without mutual interference?
A. Balun
B. Duplexer
C. Combiner
D. Circulator
A combiner permits multiple transmitters to share a common
antenna system while maintaining isolation.
5. What does “SWR” stand for in broadcast transmission lines?
A. Station Wave Ratio
B. Standard Wave Reflection
C. Standing Wave Ratio
D. Signal Wide Range
Standing Wave Ratio quantifies the ratio of reflected to forward
power in a transmission line.
6. The primary purpose of a broadcast station’s Emergency Alert System
(EAS) is to:
A. Monitor weather conditions
B. Provide entertainment updates
C. Distribute critical emergency information
D. Control transmitter power
The EAS is designed to disseminate urgent alerts from authorities to
the public.
7. In AM broadcast systems, the ground radial system predominantly
affects:
A. Receiver selectivity
B. Antenna impedance matching
C. Ground conductivity and radiation efficiency
D. Modulation depth
AM ground radials improve the conductivity around the base of
quarter-wave vertical antennas, affecting efficiency and impedance.
, 8. A broadcast antenna’s polarization that minimizes nighttime skywave
interference for AM is:
A. Horizontal
B. Vertical
C. Circular
D. Slant
Vertical polarization is standard for AM to maximize groundwave
coverage and minimize unwanted skywave interference.
9. What is the primary function of a broadcast transmitter’s phasing
network?
A. Increase modulation index
B. Decrease power consumption
C. Control phase relationships between multiple radiators
D. Measure standing waves
Phasing networks are used to shape radiation patterns by adjusting
relative phase between elements.
10. The FCC requires broadcast stations to maintain a public
inspection file that includes:
A. Personal staff resumes
B. Ownership reports and EAS testing logs
C. Ratings data
D. Advertiser contracts
Public inspection files include specific regulatory compliance
documents such as ownership reports and EAS tests.
11. Which measurement reflects transmitter frequency stability?
A. Field strength
B. SWR
C. Frequency drift in Hz
D. Modulation sensitivity
Frequency drift in hertz is the standard measure of how stable a
transmitter’s frequency remains.
12. What is the purpose of a coaxial line’s dielectric?
A. Provide shielding only
B. Increase antenna gain
C. Separate conductors and control capacitance
