    摘要: A method and apparatus for measuring an electric field distribution according to the present invention calculates a distribution of electric field intensity and its direction at arbitrary positions on the surface of the electronic apparatus or its circumference with use of data of measurement positions and measurement results of a potential distribution on a surface of an electronic apparatus. Further, it clearly indicates a flow of electromagnetic energy on the surface or in the circumference of the electronic apparatus by applying mathematical treatments to a magnetic field distribution at circumferential positions of the electronic apparatus. Thus, a distribution of high-frequency electric field generated from the electronic apparatus is measured with high accuracy.

    摘要: An arrangement to realize the functions of a radio card system in which power is transmitted to perform data communication. According to such arrangement, a delay line and a clock regenerating circuit such as PLL circuit which are previously necessary for demodulation by PSK are not necessary, and thus functions of data communication are realized by minimum hardware construction, size, cost and power consumption. Further, in a data communication system in which electric power transmission using a signal of a frequency fp and digital data communication using a carrier wave of a frequency fs are performed by radio, fs and fp are in the relationship of fs=fp/N (where N is an integer) and a phase shift P when the phase of the carrier wave is modulated by PSK is (M.times.360.degree.)/N (where M, N are integers and P is preferably not equal to 180.degree.).

    摘要: A distributed timing signal generator as a component of a per-pin architecture tester is disclosed. Start control circuits are provided per pin, and the same start signal is provided from the outside for each of the start control circuits. Each of the start control circuits then determines the start timing for at least one timing generator accommodated therein by the variable set values, and starts to control each timing generator at the thus-determined start timing. Thus, timing signals which correspond to the respective variable set values are produced from the respective timing generators with high timing accuracy and in interlock with each other. It is possible to provide timing generators for a driver, for input/output (I/O) control, and for a comparator, and in this case it is easy to obtain the respective timing signals.
