    摘要: A television receiver having a signal input terminal supplied with an interlace video signal and a signal coverter connected to the input terminal for converting the interlace video signal to a non-interlace signal to be displayed. The signal converter includes a signal inserting circuit for inserting new line signals between two successive line signals of the interlace signal, the new line signals being formed by interpolating one of the preceding and succeeding line signals in the interlace signal. A three dimensional filter is connected to the signal converter for attentuating vertical and horizontal high frequency components in the non-interlace video signal only when the non-interlace signal includes both of the vertical and horizontal high frequency components.

    摘要: A power supply route for a light source includes a first route that closes when a microcomputer is operated and a second route that opens when the microcomputer is operated. When the microcomputer stops operating, the power supply route of the light source is automatically switched from the first route to the second route. When the microcomputer is operated and a position lamp switch is turned on, current is supplied to the light source through the first route. When the microcomputer stops operating and the position lamp switch is turned on, current is supplied to the light source through the second route.

    摘要: When spatial multiplexing is performed to any of a plurality of receiving antennas included in each terminal, it becomes possible to obtain excellent receiving characteristics by combining signals received by all antennas appropriately. A receiving antenna unit 28 receives channel state information from each terminal, a channel matrix H is obtained. A transmit weight/interference coefficient calculation unit 24 calculates a transmit weight and an interference coefficient based on channel matrix. The transmit weight is input to transmit weight multiplication units 17 and 23. The interference generation unit 15 generates an interference signal based on the interference coefficient. An interference subtraction unit 13 subtracts the interference signal from a desired signal. A modulo unit 14 adds a signal so that amplitude of an information signal output from the interference subtraction unit 13 falls within a constant range. A signal multiplexing unit 18 performs spatial multiplexing to the signal performed nonlinear arithmetic.
