Methods and systems for generating an estimate of a bit error rate of a signal are provided. Methods and systems include obtaining an eye mask for a receiver, receiving a signal with the receiver, generating an eye mask probability density function of the eye mask, generating an eye diagram probability density function based on the signal, calculating a product of the eye mask probability density function and the eye diagram probability density function, summing the product of the eye mask probability density function and the eye diagram probability density function, and estimating the bit error rate of the signal based on the summing of the product of the eye mask probability density function and the eye diagram probability density function.

In embodiments, three magnetic field sensing elements are arranged equidistantly from each other to define a plane and a central axis perpendicular to the plane. The magnetic field sensing elements are configured to generate a respective output signal representing proximity of a magnetic target that is proximate to the central axis and capable of moving relative to the central axis. A processor circuit is coupled to receive output signals from each of the sensors and configured to calculate a position of the magnetic target relative to the plane.

A tunable demultiplexer accepts an input optical signal that has multiple spectral bands and provides multiple output signals. Each of the output signals corresponds to a selected one of the spectral bands. The tunable demultiplexer has at least one wavelength routing element and at least one optical arrangement disposed to exchange light with the wavelength routing element. The wavelength routing element is of the type adapted for selectively routing wavelength components of a first optical signal onto multiple second optical signals according to a configurable state.
