Abstract: A high precision fast finite impulse response (FIR) filter which periodically samples an analog input signal and holds a sequentially-replaced number of the resulting discrete-time analog values in fixed storage cells while each value is being multiplied by a number of digital weights. The discrete-time analog values are not passed through delay devices and therefore do not degrade. The weights are stored in a memory or shift register and supplied to the multipliers in a repeating sequence. A predetermined number of the weights are set to zero to increase the setup time of the analog multipliers thereby increasing the precision without slowing the clocking frequency.

Abstract translation: 一种高精度快速有限脉冲响应（FIR）滤波器，其周期性地对模拟输入信号进行采样，并将所得到的离散时间模拟值的顺序替换数量保存在固定存储单元中，同时每个值乘以多个数字权重。 离散时间模拟值不通过延迟器件，因此不会降级。 权重存储在存储器或移位寄存器中，并以重复序列提供给乘法器。 将预定数量的权重设置为零以增加模拟乘法器的建立时间，从而提高精度，而不会减慢时钟频率。

Abstract: The invention relates to a charge-coupled device, in which the channel is provided with two or more separation regions for obtaining a desired charge subdivision, for example, for a transversal filter. Due to asymmetry in the potential distribution between the outer subchannels and the central subchannels, an inaccuracy occurs in the charge distribution, which according to the invention is eliminated for the major part by locally providing the separation channels bounding the outer subchannels with an interruption.

Abstract: A sampled data filter used in a television automatic ghost cancellation system employs a single chain of cascaded delay elements and a crossbar switch matrix to implement the several different delayed sequences of samples that are used by the system to cancel several ghost signals. The rows of switch elements in the crossbar switch matrix are coupled to the individual delay elements, and the columns of the matrix are coupled to sample scaling circuitry. The scaled samples are summed to develop a psuedo-ghost signal which is combined with the input signal to cancel the ghost signal components.

Abstract: A charge transfer device (CTD) delay line comb filter for separating the frequency interleaved luminance and chrominance components of a composite video signal is provided wherein signal charges representative of the composite video signal within first and second delay lines are effectively subtracted one from the other by alternately passing them under a common, periodically clamped, normally floating sense electrode. This eliminates the need for a phase inverter, which causes imperfect separation due to having a non-zero time delay and not having exactly unity gain.
