Sub Topic Name : Production Of Amplitude Modulated Wave |
Objective measurement of the degree of change (positive or negative) in atmospheric pressure (the compression and rarefaction of air molecules) caused by sound waves.
Amplitude
"AM" is often used to refer to the medium wave broadcast band (see AM radio).
How are Amplitude Modulated Wave produced?

Radio | Changes in signal strength may be used to specify the sounds to be reproduced by a change in signal strength may be used to specify the sounds to be reproduced by a loudspeaker. |

Radio | AM works by varying the strength of the transmitted signal in relation to the information being sent. |
Wave particles exhibit dual properties. Technique used in electronic communication, most commonly for transmitting information via a radio carrier wave.
An example of AM is the violinist's TREMOLO, where the amplitude of the vibrating string is rapidly altered by a movement of the bow.
