Which type of modulation is most commonly used in FM broadcasting?
Answer: Frequency Modulation
FM broadcasting uses frequency modulation, where the frequency of the carrier signal varies with the amplitude of the input signal.
What does ERP stand for in broadcasting?
Answer: Effective Radiated Power
ERP stands for Effective Radiated Power, which is the amount of power a transmitter appears to radiate when antenna gain is considered.
What component is used to match the impedance between a transmitter and an antenna?
Answer: Antenna tuner
A transmission line or matching network ensures maximum power transfer by matching the impedance of the transmitter to the antenna.
Which frequency band is typically used for FM radio broadcasting in the U.S.?
Answer: 88 MHz - 108 MHz
The FM broadcast band in the United States ranges from 88 MHz to 108 MHz.
What is the function of a broadcast transmitter?
Answer: Generate and amplify RF signals
