Why does FM have a greater broadcast range?

Why does FM have a greater broadcast range?

Each FM station is allocated 150 kHz of bandwidth, which is 15 times that of an AM station. This means that an FM station can transmit 15 times as much information as an AM station and explains why music sounds so much better on FM.

Why is my radio not picking up FM stations?

There are multiple issues that could cause a radio to not pick up an AM / FM signal. In most cases it’s due to faulty wiring, a loose ground wire or the wiring running to and from the antenna. However, it’s also possible that an internal component inside the radio such as an electrical relay has been damaged.

What are the frequency limits of the AM broadcasting band?

The frequency band used for AM radio is about 550 to 1720 kHz. This is the range of carrier frequencies available. The information transmitted is music and talk which falls in the audio spectrum.

Why are FM radio stations limited to 50 kHz in some countries?

A few countries, such as Italy, which have heavily congested FM bands, still allow a station on any multiple of 50 kHz wherever one can be squeezed in. The 50 kHz channel spacings help prevent co-channel interference, and these take advantage of FM’s capture effect and receiver selectivity.

What is the frequency range of the FM band?

The band is divided into 100 channels, each 200 kHz (0.2 MHz) wide. The center frequency is located at 1/2 the bandwidth of the FM Channel, or 100 kHz (0.1 MHz) up from the lower end of the channel. For example, the center frequency for Channel 201 (the first FM channel) is 88.0 MHz + 0.1 MHz = 88.1 MHz.

Why do FM radio waves have less range than AM radio waves?

Originally Answered: Why do F.M. radio waves have less range than A.M. radio waves and why are they are less able to travel around obstacles such as hills and large buildings? As others have said, the difference is because of the wavelength and has nothing to do with the modulation method.

What is small scale use of the FM broadcast band?

Small-scale use of the FM broadcast band 1 Assistive listening. Some assistive listening devices are based on FM radio, mostly using the 72.1 to 75.8 MHz band. 2 Microbroadcasting. 3 Clandestine use of FM transmitters.
