Abstract: PURPOSE:To obtain the high speed low distortion buffer circuit in an angular frequency range over the cut-off angular frequency or over of a current amplifi cation factor of a transistor(TR) by detecting an output voltage with an emitter follower circuit and controlling the differential amplifier circuit with the voltage. CONSTITUTION:A current gain of a differential amplifier circuit 51 is expressed nearly to be 1/R1, where R1 is a resistance of a resistor R1 and an AC component iC of a collector current of a TR 8 is expressed as equation I. v0' in the equation I is an AC voltage component of the base of the TR 8 and equal to an output voltage v0'. The AC components of the emitter currents of the TR 2 are zero, that is, iC+iB=0 and when the resistance R1 is obtained from equations II, I, equation III is obtained. The base current iB of the TR 1 is supplied from the TR 8 in the case of omega>omegaB by deciding the R1 with a relation of an angular frequency omega=OFF angular frequency omegaB.

Title: Radio line controlling system
Inventor: MATSUO YOSHITAKE
IPC: H04Q7/38
Filed: 1983-01-21
Abstract: PURPOSE:To keep a mobile communication even with the presence of an interfering radio wave or the like by adding a interfering radio wave detector and a constant period generator controlling an idle signal transmitter so as to transmit an idle line signal at each prescribed period when the interfering radio wave is detected to a fixed station. CONSTITUTION:The idle line signal transmitter 1 transmits an idle line signal to whole mobile bodies when no signal comes from a mobile body. A signal detecto 2 supervises a common line, and stops the operation of the transmitter 1 when the signal transmission of the mobile body is detected. An interfering radio wave detector 3 discriminates it as an interfering radio wave when the incoming radio wave is only the radio wave and no signal exists. The prescribed period generator 4 controls the idle line signal transmitter 1 when the detected output of a interfering radio wave is received from the interfering radio wave detector 3 and transmits the idle line signal at each prescribed period. Thus, even if a interfering radio wave exists, the mobile body having excellent D/U can at least be kept to the state possible for communication.
