Abstract:
A scalable and compact computer system of three-dimensional subsystems (20-23) each having capacitive couplers (25) of its external surfaces for transmitting and receiving electrical signals to and from adjacent subsystems (20-23). Each surface having an electrically non-conducting substrate, one or more electrically conducting pads on the substrate, and electrical leads for coupling the pads to the subsystem's circuits. Two adjacent pads, each from a different subsystem (20-23), form a capacitive coupler (35) to carry the signals between the subsystems (20-23). The pads are covered by a low-loss dielectric material having a large dielectric constant for improved signal transmission. A differential signal may be supported using two capacitive couplers (25) to respectively carry the positive and negative signals of the differential signal. The subsystems (20-23) might be replaced or left in place when they failed. Additional subsystems (20-23) might be added to the system to expand its capacity.

Abstract:
A charge coupled device analog multiplier is used to weigh the sampled and delayed signals for a transversal filter. The digital filter coefficients for the analog multiplier can be electrically programmed and therefore dynamic time-varying systems, such as matched filters, can be designed with reduced circuit complexity. The digital filter includes means for sampling without destroying an analog signal at various points and providing voltages proportional to each sampled signal. The voltages are separately applied to a charge coupled device analog multiplier which accepts the voltages and provides means for multiplying the digital filter coefficient by the analog voltage. The multiplied sample signal is then dumped into a means for summing all of the weighted sample signals to produce an analog signal modified by the digital filter coefficients.
