摘要： A modem device enabling a single communication line to be shared by a plurality of terminal units, and needing no switching operation between the terminal units on transmission. In transmission, when a transmission-start request is supplied from a terminal unit of any channel, the state of the other channels are checked. If these other channels are all in idle state, a channel selecting signal for selecting the channel corresponding to the transmission-start request is turned on so as to couple the corresponding terminal unit to a modem section for starting the transmission. In reception, on the other hand, upon receiving a call, priority calling channel information having been set in a predetermined mode register is read out to turn on a channel selecting signal for selecting the channel indicated by that information. As a result, a terminal unit of the channel corresponding to the channel selecting signal is selected to enable the receiving operation.

摘要： A signal transmission circuit includes a switched capacitor and a control circuit. The switched capacitor includes a capacitor and a plurality of switching means. The control circuit controls the frequency or level of a control signal to be applied to the switching means of the switched capacitor. By varying the frequency of the control signal with the control circuit, the equivalent resistance of the switched capacitor can be varied. By controlling the level of the control signal with the control circuit, at least one of the plurality of switching means is held in the "off" state thereof, to substantially inhibit the signal transmission of the switched capacitor.

摘要： An indicating system includes first and second voltage comparators, first and second output circuits which are respectively supplied with output signals of the first and second voltage comparators, and first and second indicating elements which are connected to a common output terminal of the first and second output circuits. A first input terminal of the first voltage comparator is supplied with a first reference voltage, and a second input terminal thereof is supplied with a control signal. A first input terminal of the second voltage comparator is supplied with a second reference voltage, and a second input terminal thereof supplied with the control signal. When the voltage level of the control signal is higher than the first reference voltage, the first output circuit causes a current of a first polarity to flow to the common output terminal. As a result, the first indicating element is lit up, and the second indicating element is not. When the voltage level of the control signal is lower than the second reference voltage, the second output circuit causes a current of a second polarity to flow to the common output terminal. As a result, the second indicating element is lit up, and the first indicating element is not. When the voltage level of the control signal is intermediate between the first and second reference voltages, neither of the first and second indicating elements are lit up.

摘要： Either an input signal of a combining network or an output signal of an inverter arranged on a main path is fed to a side path through a mode switch in a switchable signal compressor/signal expander. Since an input terminal of a control amplifier is connected to a variable filter without passing through a signal amplifier, the deviation of the detection characteristic of a rectifier and integrator attributed to D.C. offset voltages of the signal amplifier and the control amplifier can be reduced. On the other hand, a switchable signal compressor/signal expander in another aspect of performance has a reference voltage generator for producing a D.C. reference voltage, and the output D.C. level of the control amplifier is maintained at a level approximate to the D.C. reference voltage. The other ends of first and second capacitors of the rectifier and integrator are also supplied with the D.C. reference voltage, so that the fluctuation of the detection characteristic of the rectifier and integrator ascribable to the fluctuation of the D.C. reference voltage is reduced.

摘要： A selecting information for adjusting the frequency-dividing ratio of a programable divider in a PLL synthesizer tuner is stored in the memory.In order to prevent the same selecting information from being written down in the different addresses in the memory, all of the selecting informations already written down in the memory is compared with the selecting information that is to be written down by a comparator circuit before the selecting information is written down in the memory. The output of the comparator circuit permis the selecting information to be written into the new addresses only when the selecting information that is to be written down is different from all of the selecting informations which have been written down already.
