    • In order to reduce radio interference jamming in the same channel exerting from an adjacent broadcasting area when a digitized image signal of, for example, high-definition television utilizing an idle channel in ground broadcasting of television is transmitted, a digital string such as a binary coded image signal is thinned out every predetermined digital period so as to be divided into two groups. Continuous digital strings of two series are formed by converting clock rates of the respective groups and converted into multi-value digits. Intermediate carriers are then modulated with the digital signals of the two series having their requisite bands compressed through quadrature modulation to form modulated carriers, and the modulated carriers are transmitted in bands of two divisional channels which escape from adjacent video and voice carriers, the power of which is responsible for the radio interference in the same channel. The carriers are subsequently received for reconstruction.
    • 为了减少在例如利用电视地面广播中的空闲频道的高分辨率电视的数字化图像信号发送来自相邻广播区域的相同信道中的无线电干扰干扰时,诸如二进制数 编码图像信号每隔预定的数字周期被稀疏化,从而被分成两组。 通过转换各组的时钟速率并转换为多值数字形成两个系列的连续数字串。 中间载波然后用两个序列的数字信号进行调制,这些数字信号通过正交调制压缩它们所需的频带,形成已调制的载波,并且调制的载波在从相邻的视频和语音载波中逃逸的两个分频信道的频带中传输, 它负责同一信道的无线电干扰。 随后接收载体进行重构。

    • An operational amplifier generates a power supply potential from a reference potential. An impedance adjuster adjusts an output impedance of the operational amplifier in accordance with a control signal. A charge accumulator accumulates an output charge of the operational amplifier whose impedance is adjusted by the impedance adjuster. A comparator compares an output voltage of the operational amplifier before the impedance adjustment by the impedance adjuster and the output voltage of the operational amplifier after the impedance adjustment by the impedance adjuster to each other, and the comparator further generates the control signal in accordance with a result of the comparison so as to output the generated control signal to the impedance adjuster.
    • 运算放大器从参考电位产生电源电位。 阻抗调节器根据控制信号调整运算放大器的输出阻抗。 电荷累加器累积运算放大器的输出电荷,其阻抗由阻抗调节器调节。 比较器在通过阻抗调节器进行的阻抗调整之后,将由阻抗调节器进行的阻抗调整之前的运算放大器的输出电压与运算放大器的输出电压进行比较,并且比较器进一步根据 比较结果,将所生成的控制信号输出到阻抗调节器。
