A radio wave of a specific frequency that is modulated or changed in some way in order to transmit data. The amplitude of the carrier wave can be increased—for example, to indicate a one or zero of ...

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...

FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to ...

permit the instantaneous transfer of the modulated signal over distances. Reception or DEMODULATION of the transmitted signal by a RECEIVER occurs by separating the information signal from the carrier ...

That outputs both the audio signal and a 40 kHz carrier signal ... He took care to transmit a clear signal by watching the modulated wave on an oscilloscope, looking for over-modulation and ...
