Abstract: PURPOSE:To simply and economically transmit control signals, by transmitting a transmission diversity control sgnal through the use of a vacant bit in a main signal transmission frame of a digital radio transmission system. CONSTITUTION:An output of a modulator 1 is divided into two at a 2-branching circuit; one is transmitted from a transmission antenna 5 via a transmitter 4 and the other is transmitted from a transmission antenna 9 via a transmitter 7 after phase control at an infinite phase shifter 6. After those signals are amplified at a receiver 12, they are divided into two at a 2-branching circuit 13; one is applied to a demodulator 15 and the other is applied to a phase difference or amplitude distortion detecting circuit 16, and an SD control signal for the phase shifter 6 is generated at an SD (space diversity) control circuit 18. This SD control signal is applied to a time division multiple write circuit 35 via a line controller and written in a specified vacant bit located in the main signal transmission frame. The SD signal transmitted via a modulator 21, a transmitter 22, and a transmission antenna 24 is read out at a time division multiple readout circuit 37 and applied to the phase shifter 6.

Title: Clock signal input system
Inventor: SUGIYAMA HIROSHI
IPC: G01R31/28
Filed: 1985-08-09
Abstract: PURPOSE:To enable the implementation of a scanning test operation accuracy, by providing a gate in a receiving route for clock signals for normal operation to cut off the gate before a clock signal for scanning test is inputted. CONSTITUTION:In the normal operation, the clock signal (tck) for a test is set at the logical '0'. As a result, the output signal (q) of an FF1 to be inputted into an input terminal A of a gate 4 is outputted to an output terminal C as intact and transmitted to a clock terminal CK of an FF3. When a scanning test is carried out, by signal (tck) is set at the logical '1'. Consequently, the clock signal (ck) to be transmitted to the clock terminal CK of the FF3 from the output terminal C of the gate 4 is also set at the logical '1' regardless of the logical value of the output signal (q) of the FF1. Under such a condition, when a scanning data signal (sd) is inputted into a scanning data terminal SD of the FF1 while a scanning clock signal (sck) is inputted into each of the FFs 1-3, the scanning data signal (sd) is transferred through the FFs 1-3 synchronizing the scanning clock signal (sck).
