What is the maximum frequency deviation allowed in FM broadcasting?

Explanation: Maximum frequency deviation allowed for commercial FM broadcast is 75KHz. Therefore approximate bandwidth allowed is 2*75= 150KHz.

What are the range of frequencies for the FM band?

about 88 to 108 MHz
The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum. The full audio spectrum ranges form 20 to 20,000 Hz, but FM radio limits the upper modulating frequency to 15 kHz (cf.

What is the effect of increasing modulation index in FM?

As the modulation index increases for frequency modulation (FM), the number of significant sidebands increases, but the sidebands’ total average power remains constant.

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.

What is the peak frequency of a commercial FM signal?

Commercial FM signals use a peak frequencydeviation of ∆f= 75 kHz and a maximumbaseband message frequency of fm= 15 kHz.Carson’s rule estimates the FM signal bandwidthasBT= 2(75 + 15) = 180 kHz which is six timesthe 30 kHz bandwidth that would be required forAM modulation.

What is the bandwidth of the center frequency of the 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.

How do you calculate the bandwidth of an FM signal?

The following formula, known as Carson’sruleis often used as an estimate of the FM signal bandwidth: BT= 2(∆f +fm) Hz (16) where ∆f is the peak frequency deviation and fmis the maximum baseband message frequency component.
