摘要:
The present invention solves the conventional problems and has an object to provide a matched filter system of high process in speed, a small size and low electric power consumption. The matched filter circuits of each matched filter set is allocated different n combinations of M/n digits selected from the M length PN code sequence picking one out of every n digits, cyclically performs sampling every 1 chip time duration the input signals to be inputted to each set constructed by matched filter circuits by n sets each of which including n matched filter circuits, and calculates the sum of outputs of all matched filter circuits.

Power supply sockets of a distributing system of interior power supply wiring are provided with a communication distributing terminal, and apparatus (A1-An) are provided with a terminal unit 2 for connection to a communication line CL. A unique address is assigned for the terminal unit 2. A communication line CL is provided with a timing clock supply line TL, a unique address communication line AL, and a local area network (LAN) line LL, thereby connecting the apparatus (A1-An) connected to the power supply socket to the communication line CL. The unique address of the terminal unit 2 connected to the communication line CL is transmitted to the unique address communication line AL, and communication with the terminal unit 2 is controlled through the LAN line LL by the communication control unit 1. The terminal unit 2 transmits its own unique address to the unique address transmission line AL during a predetermined address registration period, when it failed to find its own unique address in unique addresses transmitted from the communication control unit 1. Thereby realizes very easy communication between the apparatus (A1-An).

MOS inverter forming method within a large scale integrated circuit (LSI) for providing a pair of inverter circuits with the same characteristics each of which comprise a plurality of MOS inverters comprising common semiconductor layers (PL1,PL2) elongated along said MOS inverters, at least one of said semiconductor layers being provided with a strangulation or constricted portion (S1,S2) such that the channel width of at least one MOSFET forming said MOS inverters is reduced.
摘要:
A complex number calculation circuit for directly multiplying a complex number of an analog signal by a digital complex number as a multiplier. A capacitive coupling is used with a plurality of parallel capacitances corresponding to weights of bits of real and imaginary parts of the multiplier. Sign of the multiplier is represented by selection of outputs paths. A complex number calculation circuit for calculating approximated absolute value suitable for an analog architecture. Inverter circuits are used for linear inversion of analog values, and capacitive couplings are use for weighted addition. Analog maximum and minimum circuits with parallel MOSs are used for maximum and minimum calculation.
