    • The A/D converter converting an analog input signal into a digital output signal is constructed with a band pass ΔΣ modulator. The band pass ΔΣ modulator includes: a resonator showing a band-pass characteristic at a predetermined frequency and an attenuation characteristic at another frequency; a quantizer; and a local D/A converter. A signal of difference between the analog input signal and a local analog signal of the local D/A converter is supplied to the resonator. The A/D converter further includes an adder for supplying the analog input signal to an input of the quantizer. In addition, signal transmission circuits for reducing the influence of spike noise of the quantizer on the input to the resonator are connected between an input of the adder and an input of resonator selectively. The A/D converter constructed with the band pass ΔΣ modulator is improved in S/N ratio.

    • A local area network system which allows a plurality of subscriber terminals to communicate with each other via a central station, and a router unit therefor. Logical addresses assigned to the individual subscriber terminals and physical addresses associated therewith are previously registered to an address table. The central station receives transmission data from a first subscriber terminal, to which data a logical address of a second subscriber terminal is affixed. A physical address reading unit, as part of the central station, reads out a physical address corresponding to the received logical address by consulting the address table. When the received logical address was incorrect, the physical address reading unit cannot find the corresponding entry in the address table, and if that is the case, the received transmission data will be discarded. When the received logical address was found in the address table, the data transfer unit forwards the transmission data to the second subscriber terminal by using the logical address affixed to the received transmission data and the physical address that is read out by the physical address reading unit.
    • 允许多个用户终端经由中心站彼此通信的局域网系统及其路由器单元。 分配给各个用户终端的逻辑地址和与之相关的物理地址预先注册到地址表。 中央站接收来自第一用户终端的传输数据,附加第二用户终端的逻辑地址的数据。 物理地址读取单元作为中心站的一部分,通过查询地址表读出与接收的逻辑地址对应的物理地址。 当接收到的逻辑地址不正确时,物理地址读取单元在地址表中找不到相应的条目,如果是这样的话,接收的传输数据将被丢弃。 当在地址表中找到接收到的逻辑地址时,数据传送单元通过使用附加到接收到的传输数据的逻辑地址和由物理地址读取单元读出的物理地址将传输数据转发到第二用户终端 。
