·          process of varying one or more properties like frequency, amplitude, phase of periodic waves.

• Amplitude Modulation

• Frequency Modulation

• Modulation

• Phase Modulation (PM)

a signal that causes a variation of some of the properties of the carrier.

• Carrier

when you vary the amplitude of the carrier in proportion to the information signal.

• Phase Modulation (PM)

• AMPLITUDE MODULATION SIDEBANDS

• Envelope

These sidebands also carry information being transmitted by an electronic communication device resulting to a________

• carrier frequency

• AMPLITUDE MODULATION SPECTRUM

• AMPLITUDE MODULATION ENVELOPE

·          is the operating frequency or the center frequency of a certain communication medium which is used to modulated a baseband frequency or information from the sender.
