Abstract
A system and method is disclosed for providing real time signal to noise computation for a 100 Mb Ethernet physical layer device. A slicer module obtains a slicer error signal in the physical layer device and generates a signal that represents a square of the slicer error signal. A variance computation unit uses the signal that represents the square of the slicer error signal to calculate a value of variance of a histogram of the physical layer device by continuously accumulating a plurality of values of the square of the slicer error signal for a selected period of time. A real time signal to noise ratio is then computed using the calculated value of the variance of the histogram of the physical layer device.
