In accordance with one embodiment of the present invention, a power spectral density (PSD) mask for spectral shaping of a dual bit map (DBM) mode downstream transmission is provided. The PSD mask is represented by the equation:.times..times..function..pi..times..pi..times..times..times.- .circleincircle..circleincircle..infin. ##EQU00001## where PSD.sub.DBMsOL represents the PSD mask, K.sub.ADSL.sub.--.sub.OL represents a constant value, C represents a constant value, f represents a frequency of the downstream transmission, f.sub.0 represents a constant value, f.sub.LP3dB represents a 3 decibel (dB) low pass frequency and f.sub.f.sub.HP3dB represents a 3 dB high pass frequency. K.sub.ADSL.sub.--.sub.OL preferably has a value between 0.0900 watts and 0.1200 watts and more preferably has a value of 0.1104 watts. The constant f.sub.0 preferably has a value between 2.100 megahertz and 2.300 megahertz and more preferably has a value of 2.208 megahertz. The constant f.sub.LP3dB has a value substantially equal to ##EQU00002## The constant f.sub.HP3dB has preferably has a value between 100 kilohertz and 150 kilohertz and more preferably has a value of 130 kilohertz. The constant C preferably has a value between 0.1 and 10 and more preferably has a value of 2.       Recently Added Patents Vehicle user interface systems and methods Styling cabinet Engine characteristic estimation method, and computer readable medium Monitoring a vital parameter of a patient with "in-situ" modulation scheme to avoid interference Aquaculture vessel Data transmitting and receiving system, transmitting apparatus and receiving apparatus Method and system for transferring control of a user interface of a content distribution system   Randomly Featured Patents Cartridge-needle unit having retractable needle Post forming semi-finished product for the manufacture of moulded parts resistant to bending Very high energy, high stability gas discharge laser surface treatment system Method for manufacturing yoke of electric rotating machine Titanium dioxide pigment coated with cerium cations, selected acid anions, and alumina In vitro method for the diagnosis of cardiovascular functionality of bone marrow precursor cells (BMPS) and/or blood-derived circulating precursor cells (BDPS) Magnetic resonance spectroscopy method Robot structure Antivibration device and mechanical assembly comprising such antivibration device Separator sub with annular flow passage © 2006-2008 PatentGenius.
