    • A cylindrical coaxial electrical connector comprising a male portion and a female portion, the connector being of the type that includes an intermediate strip of contact springs of elastic material, the springs being united at their ends by two continuous side strips and each having a succession of tongues extending the side strip outwards, said intermediate strip being placed in an annular housing in one or other of the two portions, said housing having two side flanks with walls that are perpendicular to the axis of the connector, wherein each elastic tongue has a first face bent towards the bottom of the housing and then bent in the opposite direction to form an end face rising up towards the outside of the housing, the end of said face bearing against the side flank of said annular housing.

    • Digital video signals are subjected to band limiting by a high pass filter with a pass band terminating somewhat above half of the digital sampling frequency. The filtered signal is in effect subtracted from the original signal in an addition circuit with suitably phased inputs in order to make available a substitute signal of the interpolation low pass filtered kind. A circuit for determining the presence of an erroneous digital word accepts the high pass filtered signal, differentiates it twice and then digitally rectifies it in order to detect a possible maximum at half the sampling rate. When such a maximum is found, a changeover switch is caused to substitute the interpolation-low-pass-filtered signal for the orginal signal. Only a single digital filter is necessary for this operation. The high pass filter is a FIR filter of, for example, eleventh order and the middle coefficient is in effect changed from minus 1 to 0 when the delay equalized original signal is added to the output of the high pass filter.
    • 数字视频信号通过高通滤波器进行频带限制,该通带滤波器的终端略高于数字采样频率的一半。 滤波后的信号实际上在具有合适的相位输入的加法电路中从原始信号中减去,以便提供内插低通滤波种的替代信号。 用于确定错误数字字的存在的电路接受高通滤波的信号,将其区分两次,然后对其进行数字整流,以便以一半采样速率检测可能的最大值。 当发现这样的最大值时,使用切换开关代替原始信号的内插低通滤波信号。 此操作只需要一个数字滤波器。 高通滤波器是例如第11级的FIR滤波器,当将延迟均衡的原始信号添加到高通滤波器的输出时,中间系数实际上从负1变为0。
