Abstract
A lossless, bi-directional bus tap for connecting peripheral devices to a common bus. The tap comprises first and second combiner/divider (C/D) networks each having a first input/output (I/O) port which are connected to the two ends of an interruption in the common bus and N second ports with Y db isolation between the I/O port and any of the N second ports and X db isolation between any two of the N second ports. The tap is responsive to an input signal supplied to the I/O port or to input signals supplied to the N second ports to produce, respectively, divided signals on the N second ports and a combined signal on the I/O port. Also provided are two Z db gain amplifiers connected in reverse direction of amplification between first ports of the N second ports of the two C/Ds and between second ports of the N second ports of the two C/Ds, where X>Z and Z.congruent.2Y, and logic bi-directionally connecting a peripheral device to third ports of the N second ports of the two C/Ds.
