What type of wave is used by radio stations in broadcasting their programs?
FM radio waves are also used for commercial radio transmission in the frequency range of 88 to 108 MHz. FM stands for frequency modulation, which produces a wave of constant amplitude but varying frequency.
How do radio stations measure number of listeners?
Radio listenership is tracked through what is called an AQH figure or Average Quarter-Hour figure. This number is based on the average number of people listening to a radio station for five minutes during any given 15-minute period.
How is radio audience measured?
Radio Audience measurement specifically relates to radio listenership. The “radio audience” definition varies by market, but a typical definition is that to be a listener to a specific station, said individual should have been listening for a set period of time (often 5 minutes) within a given quarter hour segment.
How do radio stations use radio waves?
In radio broadcasts, sounds are encoded in radio waves, and then the waves are sent out through the atmosphere from a radio tower. A radio receiver detects the waves and changes them back to sounds. For TV broadcasts, waves are encoded with frequency modulation, and pictures are encoded.
What do radio ratings mean?
Rating: An estimate expressed as a percent of a universe. It is a percentage of the people in the market who listen to a specific station. Share: An estimate of the persons using radio in a market (PUR) who are tuned to a particular station. Arbitron reports these numbers. AQH persons:.
How do you read radio ratings?
AQH ratings are used to determine Cost per Point and can be compared to TV ratings. It is calculated by dividing the number of Average Quarter-Hour Persons by the population within the same sex/age group. The percentage (or share) of radio listeners within a given demographic and daypart.
How do TV and radio waves work?
Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones.

Why don’t AM radio stations have channel numbers?
AM radio is the exception in that it never has used channel numbers. Well, it’s just terminology relevant to the industry. They’re called radio stations because operate on their own frequency, either through amplitude modulation and frequency modulation.
