    • A plurality of generator polynomials are prepared for error correction and stored in a table by assigning a specific table number to each generator polynomial. Each generator polynomial provides a different error correction capability so that a different number of error correction bits are added to each set of transmission data. For radio communication, an electric field intensity is first measured, and in accordance with this electric field intensity, a generator polynomial to be used at that time for error correction calculation is determined. It is therefore possible to change the number of error correction bits in accordance with the environment at that time and to perform efficient error correction. For example, if a base station is in a near area, an error rate is small so that the number of addition bits is reduced.
    • 通过为每个生成多项式分配特定的表号,准备多个生成多项式用于纠错并存储在表中。 每个生成多项式提供不同的纠错能力,使得不同数量的纠错位被添加到每组传输数据。 对于无线电通信,首先测量电场强度,并且根据该电场强度,确定当时用于纠错计算的生成多项式。 因此,可以根据当时的环境改变纠错位的数量并执行有效的纠错。 例如,如果基站处于近区域,则误码率小,使得加法位数减少。

    • A sawtooth wave generated in a sawtooth wave generator circuit of a vertical deflection circuit assumes a predetermined maximum voltage at the start of a vertical scan and a minimum voltage which changes depending on a vertical cycle period at the end of the vertical scan. A pulse generator generates a sampling pulse at the end of the vertical scan so that the sawtooth wave voltage at the end of the vertical scan is sampled by the sampling pulse. The sampled sawtooth wave is held until a next sampling pulse is generated so that a D.C. voltage which changes in accordance with the vertical cycle period is produced. The sawtooth wave voltage is level-shifted by a level shifting circuit and thereafter amplified before it is supplied to a vertical deflection coil. The amount of shift by the level shifting circuit is controlled by the D.C. voltage so that the sawtooth wave having a stabilized D.C. component is amplified. Accordingly, a vertical deflection circuit free from D.C. component variation can be derived and the swing of image can be suppressed.
    • 在垂直偏转电路的锯齿波发生器电路中产生的锯齿波在垂直扫描开始时呈现预定的最大电压,并且根据在垂直扫描结束时的垂直周期周期而变化的最小电压。 脉冲发生器在垂直扫描结束时产生采样脉冲,使垂直扫描结束时的锯齿波电压由取样脉冲采样。 采样的锯齿波被保持直到产生下一个采样脉冲,从而产生根据垂直周期周期变化的直流电压。 锯齿波电压通过电平移位电路进行电平移位,然后在提供给垂直偏转线圈之前被放大。 由电平移位电路的移位量由直流电压控制,使得具有稳定的直流分量的锯齿波被放大。 因此,可以导出没有D.C.分量变化的垂直偏转电路,并且可以抑制图像的摆动。

    • A pair of output transistors forming a single-ended push-pull circuit are alternately turned on and off at a vertical cycle to supply a vertical deflection current to a vertical deflection yoke. A low voltage winding is wound on a horizontal flyback transformer connected to a horizontal output transistor. First and second rectifying circuits are provided for rectifying and filtering a horizontal scan period portion and a horizontal flyback portion, respectively, of the voltage developed across the winding, and d.c. outputs of the rectifying circuits are fed to the push-pull circuit as operating power therefor. The first rectifying circuit includes a capacitor-input filter circuit while the second rectifying circuit includes a choke-input filter circuit, a critical current of which choke-input filter is established between a maximum current and a minimum current required for the push-pull circuit.
