Found 2 Articles for Amplitude Modulation

Magnitude and amplitude are frequently used interchangeably to describe characteristics of numbers in common parlance. Both words are interchangeable, according to a thesaurus. Yet in engineering, they signify two distinct things, therefore it's crucial to know the difference. The maximum positive or negative value to which a variable deviates from its mean is referred to as its amplitude. It is just the farthest a vibration or oscillation may go from its stable location (zero level). Because of this, signal amplitudes can either be positive or negative. On the other hand, a variable's magnitude is a measurement of how much its ... Read More

In data communication, modulation is a process of changing the characteristics of a data carrier signal so that it can travel the desired distance for data transmission. Modulation is a necessary process in communication systems to increase the reliability of data communication. In the modulation process, an additional signal, called carrier signal, is generated that can go up to long distances, then the message signal is superimposed with this carrier signal, so that the carrier signal transmit the message signal over a long distance without getting affected by the external disturbances. This process is known as modulation. There are several ... Read More
