Amplitude modulation - Wikipedia, the free encyclopedia (1958 words) |
 | Amplitude modulation (AM) is a form of modulation in which the amplitude of a carrier wave is varied in direct proportion to that of a modulating signal. |
| AM is commonly used at radio frequencies and was the first method used to broadcast commercial radio. |
| AM radio's main limitation is its susceptibility to atmospheric interference, which is heard as static from the receiver. |
| AM Statistical Software (290 words) |
| AM is a statistical software package for analyzing data from complex samples, especially large-scale assessments. |
| AM offers sophisticated statistics with an easy-to-use drag and drop interface, and an integrated help system that explains the statistics as well as how to use the system. |
| AM is still in Beta release, though we have put it through substantial testing. |
