Title: Mixed mode adaptive analog receiving architecture for data communication
Inventor: LEE KATHLEEN OTIS
IPC: H04L25/03
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To adaptively compensate gain fluctuation, inter-code interference, base line fluctuation, flat loss and DC offset by providing a feedback loop, which controls the transmission function of a compensation circuit in response to an error signal and is provided with a digital integrator, coupled between an adapted circuit and at least one compensation circuit. SOLUTION: A comparator 58 of a receiver front end detects whether a value in each time slot of an incoming data signal expresses digital '1' or '0' and a timing recovery circuit 60 captures the timing of the incoming signal, synchronizes a reception station to the incoming data signal and further uses data by outputting them to the other circuit for decoding. A high-pass filter 50 is a first adaptive compensation circuit on a data path and this compensates the base line fluctuation together with a low-pass filter 62. An automatic gain control(AGC) circuit 52 is an adaptive correction circuit for correcting the flat loss.

Abstract: PURPOSE:To obtain a cable withstanding the external strong magnetic field and the high temperature by covering signal lines made of the first superconducting material and insulating materials with the second superconducting material with the critical magnetic field intensity, critical absolute temperature or critical current density higher than those of the first material. CONSTITUTION:A pair of two signal lines are both constituted of the first superconducting material 10, and both lines are insulated from each other by an insulating material 12. They are covered by an insulating material 13 then by the second superconducting material 11, and the whole is finally covered by a covering material 14. The critical magnetic field intensity, critical absolute temperature or critical current density of the second superconducting material 11 is selected higher than those of the first superconducting material. According to this constitution, when the external magnetic field intensity is increased and the material 10 for signal lines can not maintain the superconductive state, for example, the second material maintains the superconductive state, and the external magnetic field does not infiltrate into the inside due to the complete diamagnetic property. When the external magnetic field exceeds the critical point of the material 11, the superconductive state of the signal lines broken. It is the same also for the absolute temperature and current is density.
