What is the upper frequency of a signal with bandwidth of 6 MHz?

What is the upper frequency of a signal with bandwidth of 6 MHz?

The maximum frequency of the audio signals used for modulating the carrier wave is 5 KHz.

What is the bandwidth of AM and FM frequencies?

FM has better sound quality due to higher bandwidth. AM radio ranges from 535 to 1705 KHz (OR) Up to 1200 bits per second. FM radio ranges in a higher spectrum from 88 to 108 MHz. (OR) 1200 to 2400 bits per second.

How many radio channels can be transmitted using FM transmission window?

The FM broadcast in the United States starts at 88.0 MHz and ends at 108.0 MHz. The band is divided into 100 channels, each 200 kHz (0.2 MHz) wide.

What is the bandwidth of the FM signal in kHz?

Commercial FM signals use a peak frequency deviation of ∆f = 75 kHz and a maximum baseband message frequency of fm = 15 kHz. Carson’s rule estimates the FM signal bandwidth as BT = 2(75 + 15) = 180 kHz which is six times the 30 kHz bandwidth that would be required for AM modulation.

What are AM channels used for?

AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as “AM band”) transmissions, but also on the longwave and shortwave radio bands.

What is the upper frequency of a signal with bandwidth of 60 Mhz if the lower frequency limit is 54 Mhz?

Q. What is the upper frequency of a signal with a bandwidth of 6Mhz, if the lower frequency limit is 54Mhz? Upper frequency = bandwidth + lower frequency = 54Mhz + 6Mhz = 60Mhz.

What is the bandwidth of AM signal?

The information transmitted is music and talk which falls in the audio spectrum. The full audio spectrum ranges up to 20 kHz, but AM radio limits the upper modulating frequency to 5 kHz. This results in a maximum bandwidth of 10 kHz.
