    • In a projection type display apparatus including a blue CRT display apparatus with low luminous efficiency and low luminous efficiency, the present invention seeks to improve contrast while suppressing the fall in brightness for red, green, and blue color as a whole. In the projection type display apparatus, the images of three colors outputted from three monochrome CRT display apparatuses 10R, 10G, 10B which respectively output monochromatic video signals of red, green, and blue color, are respectively projected on a screen unit 14 via a reflecting mirror 12 so as to synthesize a image of three colors and generate a color image. The brightness of the green CRT display apparatus which outputs the green image having the highest luminous efficiency is increased, while maintaining the brightness of the blue CRT display apparatus 10B. Further, a light absorption means for tinting to reduce the increased green brightness is provided to balance the whole brightness of red, green, and blue. Contrast is improved by the light absorption means for tinting. Preferably, the red CRT display apparatus 10R is treated similarly to the green CRT display apparatus 10G.

    • In a thyristor ignition circuit, a forward voltage drop occurring in a signal path of an anode and a gate of a thyristor is reduced. An anode of a thyristor of the thyristor ignition circuit is connected to one signal terminal, and a gate thereof is connected to another signal terminal. The thyristor ignition circuit further comprises a transformer having a primary winding for receiving an ignition signal, and a first secondary winding having one end connected to a cathode of the thyristor and the other end connected to the other signal terminal. The thyristor is ignited via the cathode in response to the ignition signal applied to the transformer. A signal path is established between one signal terminal and the other signal terminal through the anode-to-gate path.

    • A portable HDTV testing device inserts a deterministic test signal having a frequency close to the symbol rate of the received HDTV signal. As the received HDTV signal is randomized prior to broadcast for synchronization purposes, the addition of the deterministic test signal to the randomized data signal is essentially equivalent to the addition of a random (or white) noise signal to an information bearing signal. The use of a deterministic test signal avoids the expense associated with a random signal generator, thus making possible an inexpensive and portable HDTV test device. To test the noise margin of a received signal, which is used to determine if the installation of the antenna and HDTV receiver is optimized, the test unit inserts known levels of the noise signal incrementally and measures the bit error rate until the bit error rate exceeds a known threshold above which proper decoding is not possible. The level of the noise signal at which the bit error rate exceeds the known threshold defines the noise margin of the received signal. The higher the noise margin, the stronger the received signal, and the closer to optimum the installation of the HDTV antenna and receiver. Thus, the present invention makes possible an inexpensive and portable HDTV test unit.
    • 便携式HDTV测试装置插入具有接近接收的HDTV信号的符号率的频率的确定性测试信号。 由于接收的HDTV信号在广播之前被随机化以用于同步目的,所以将确定性测试信号添加到随机数据信号基本上等于将随机(或白噪声)信号添加到信息承载信号。 使用确定性测试信号避免与随机信号发生器相关联的费用,从而使廉价且便携式的HDTV测试设备成为可能。 为了测试接收信号的噪声容限,用于确定天线和HDTV接收机的安装是否被优化,测试单元递增地插入噪声信号的已知电平,并测量误码率,直到误码率超过 一个已知的阈值,超过此阈值是不可能进行适当的解码。 误码率超过已知阈值的噪声信号的电平定义了接收信号的噪声容限。 噪声容限越大,接收信号越强,越接近HDTV天线和接收机的安装。 因此,本发明使得便宜且便携式的HDTV测试单元成为可能。
