Electromagnetic waves with high frequencies Electromagnetic waves with high frequencies have short wavelengths and waves with low have short wavelengths and waves with low frequencies have long wavelengths. frequencies have long wavelengths. HertzHertz RF signals are typically depicted as RF signals are typically depicted as sinusoidal (sine) waves that vary in amplitude sinusoidal (sine) waves that vary in amplitude over A frequency of one cycle per second is called A frequency of one cycle per second is called a hertz.

7 One hertz simply means "one per second" One hertz simply means "one per second" (1/s). (1/s). HertzHertz Some of the common frequency nomenclatures Some of the common frequency nomenclatures that we use in the cable industry are:that we use in the cable industry are: Kilohertz (KHz)Kilohertz (KHz)= 1,000 cycles/second = 1,000 cycles/second (One thousand Hertz)(One thousand Hertz)20(One thousand Hertz)(One thousand Hertz) Megahertz (MHz)Megahertz (MHz)= 1,000,000 cycles/second = 1,000,000 cycles/second (One million Hertz)(One million Hertz) Gigahertz (GHz)Gigahertz (GHz)= 1,000,000,000 = 1,000,000,000 cycles/second (One billion Hertz)cycles/second (One billion Hertz)HertzHertz21 Frequency Use Authorization Frequency Use Authorization The Federal Communications Commission The Federal Communications Commission (FCC) is a government agency responsible for (FCC)
