  • Publication number: 20060057982
    Abstract: An output level of a transmission apparatus 1 is determined, depending on an attenuation amount of an attenuator 30, a gain of one of a high output level amplification section 17 and a low output level amplification section 18, which is used. A reference voltage Vref(H) is discontinuously changed. Depending on the magnitude of the reference voltage Vref(H), it is determined which of the amplification sections 17, 18 is used, and the attenuation amount of the attenuator 30 and the gain of the amplification section 17, 18 are also determined. When the magnitude of the reference voltage Vref(H) is changed, a sum of the attenuation amount of the attenuator 30 and a gain change amount of a switch amplification section 19 is substantially zero.

  • Publication number: 20060053118
    Abstract: A communication terminal device includes a communication unit, an archive determination unit, an archive data creating unit and an interface unit. The communication unit receives data from another communication terminal device. The archive determination unit searches whether or not archive information is included in the data received by the communication unit to determine whether or not the received data is archive data. When the archive determination unit determines that the data is not archive data, the archive data creating unit processes the data into archive data by adding archive information to the data. The interface unit transmits the archive data to another different communication terminal device.
