摘要： To implement a key telephone system through an IP (Internet protocol) network, if real-time broadcast information is transmitted by multicast communications, restriction to prevent a rapid increase in network traffic is received, an additional special protocol is required, and it is hard to ensure the confidentiality of information. If real-time broadcast information is transmitted by unicast communications, transmission processing is centralized on a broadcast information transmission apparatus, the traffic becomes enormous, and a broad communication band and a high processing capability become necessary. Therefore, a transmission dedicated apparatus is provided between a broadcast information transmission apparatus and a terminal for distributing the transmission function and traffic. The broadcast information transmission apparatus needs only to manage the transmission dedicated apparatus. A plurality of terminals, etc., can be connected to the transmission dedicated apparatus. Further, a transmission dedicated apparatus can also be connected as a subordinate node to the transmission dedicated apparatus.

摘要： The invention provides a waveform information display apparatus, wherein the property of waveform data is grasped by the light of nature. Specifically, digital waveform data stored in a memory is split into a plurality of time segments, and compressed display data is generated in each of the time segments. A waveform is displayed on the screen by the compressed display data. Then, a property specified for the waveform is extracted from the digital waveform data in each of the time segments, and a value expressing the specified property in the time segment is obtained on the basis of the extracted property. Further, a waveform display portion in each of the time segments displayed on the screen on the basis of the compressed display data in each of the time segments is displayed in a state wherein the obtained value expressing the property is reflected on the waveform display portion.

摘要： An amplifying circuit with a level-shift circuit is disclosed. An amplifying unit includes two stages of differential amplifiers cascadedly connected. A differential amplifier of the first stage has a pair of differential input terminals. The differential amplifier of the last stage has a pair of differential output terminals. A level-shift circuit constituted of a couple of level-shifters is connected to the output terminals. The level-shift circuit level-shifts the DC level of the differential output from the amplifying unit. The level-shift circuit has a pair of output terminals to deliver the level-shifted differential output. A DC-dummy dummies the DC operation of the differential amplifier of the last stage. The DC-dummy has the power supply in common with the differential amplifier of the last stage. A level-shifter shifts the output level from the DC-dummy and delivers the level-shifted dummy output. The constitution of the level-shifter is the same as one of a couple of level-shifters in the level-shift circuit. An operational amplifier keeps a voltage of the level-shifted dummy output constant. Therefore, the operational amplifier supplies the voltage power in common to the differential amplifier of the last stage and the DC-dummy.
