Even after a long briefing with the company, I still donât know how it works. One explanation said that I should view it as a multidimensional QAM. Here is what MagnaComâs release said about WAM: âWAM technology is a pure digital new modulation scheme, using spectral compression that improves spectral efficiency.The spectral compression enables an increase in the signaling rate thereby affording the use of lower order alphabet, which reduces complexity.ave modulation, the term seems to be intuitively misleading, like the carrier is a WAVE that is undergoing MODULATION. The term doesn't imply anything revealing to its nature. Maybe we can derive the nature of this WAM scheme from the benefits it gives or from some of the descriptions.
Alzheimer's disease is a common cause of dementia and its associated symptoms. One of the the main and often the first symptom of Alzheimer's disease is memory problems that develop slowly over time. Symptoms that develop later include. personality changes (for example, apathy), withdrawal, and. reduced spontaneity.
This is normal, and part of what makes Alzheimerâs disease difficult to identify in its early stages. The classic distinction with Alzheimerâs is that one of the very earliest symptoms is difficulty in forming new memories â what will appear to be short-term memory loss. Other early signs can be place confusion (not recognizing familiar surroundings or becoming easily lost), difficulty with words, and trouble with basic math.
