Frequency range

A frequency range or frequency band is a range of wave frequencies. It most often refers to either a range of frequencies in sound or a range of frequencies in electromagnetic radiation, which includes light and radio waves.

Many radio devices operate within a specified frequency range which limits the frequencies on which it is allowed to transmit. The lower-bound and upper-bound frequencies are the points at which signal strength of the device falls off by 3 dB.

Music

The frequency range of a musical instrument is called ambitus.

CATV Cable Amplifier

The Frequency Range of a CATV amplifier are categorised as mentioned below;
#Low Frequency Range are 1 Hz to 150 MHz.
#Intermediate Frequency Range are 151 MHz to 299 MHz.
#High Frequency Range are 300 MHz to 50 GHz.
