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.
AMradio's main limitation is its susceptibility to atmospheric interference, which is heard as static from the receiver.
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.
