The DSP peripherals, including serial port, TDM serial port, timer, wait-state generator, interrupt generator and memory mapped I/O ports, are designed to implement the communication and control to external data.
The measured center wavelength is 1550. 85 nm, wavelength channel spacing is about 0. 81nm, 3-dB bandwidth is about 0. 35 nm. The crosstalk is about - 20dB, and the insertion loss is between 10. 4dB for the central port and 11. 9dB for the edge ports.
mm integrated flip chip ring mixer circuit is designed and simulated with HP ADS software. The simulated three ports isolation is nicer when RF is 35.1GHz and local frequency is 35GHz.
A principle of designing realizable precision interfaces between sensors and digital ports of microcontrollers and microconverters which enable one not only to measure a physical variable but also to estimate its derivative was proposed.
The sensor is inserted in a vacuum chamber; the rotating mechanism of the sensor and location of the ports in the facility enables measurements along the plasma column.
It is proposed that the compact neutron cameras be placed inside the shielding blocks located in the equatorial (nine collimators) and diverter diagnostic (seven collimators) ITER ports.
In this paper, a method based on the triangular unequality is used to explain themaximum power transfer theorem in n-ports network. This method of proof is not only rigid and terse, it can also determine directly the condition of the maximum power transfer and the supremum of the available power drawn by the terminated load. Moreover, with this method, it is not necessary to decide whether the extreme value is of local or global optimum nor is it necessary to determine whether the objective function i...
This paper analysis the Y doubly balanced ring mixer and gives ports relations in matix equatrion by using linear periodically time-varying resistance theory. The microstripline-balun is designed by computer aided method, and then tne construction of circuit and data of measurements are given.@ This microwave-component has found its application in instrument and broadband microwave receiver with good performance figure.
A prediction-decision fault analysis method is presented in this paper. If the number of faults in a circuit does not greater than the number of ports, the faults can be analysed by this method only using some algebraic computations. But if there have some loops or cut sets between these fault branches, solving a set of nonlinear equations is also necessary, though the number of variables is much decreased.
