where [P.sub.r] is the received power, W is the channel bandwidth, N is noise power, f is transmission bit rate, and erfc is the complementary error function.
The Victorian snuff box, pictured, by George Unite, hallmarked Birmingham 1895, bears the initials "ERFC" and is inscribed: "Chester Golf Club May 21 1896".
According to previous studies, the doping concentration profile of PO[Cl.sub.3] typically ranges from an error function complement (erfc) to a Gaussian distribution, with the peak dopant concentration occurring at the surface.
For example, for a Gaussian pdf, the probability of being more than three standard deviations greater than the mean is Q(3) = 0.5 x erfc(3/[square root of (2)]), where erfc is the traditional Gaussian "complementary error function." Q(3) is about 0.0013 meaning that, if 1000 circuits are simulated, we can only expect to find one value of the key output in this region.
