Abstract: A duplex signal communication channel includes first and second signal transmission lines. While a first amplifier coupled to the first signal transmission line is driver into a nonlinear region of operation, a first data signal is transmitted by the first amplifier on the first signal transmission line. The first data signal is transmitted at a multiple of a common clock frequency. A second amplifier coupled to the second signal transmission line transmits a second data signal on the second signal transmission line concurrently with the first data signal, but does so at the common clock frequency. A first receiver circuit receives the first data signal on the first signal transmission line, and a second receiver circuit receives the second data signal on the second signal transmission line. Receiving the first data signal includes extracting the first data signal from the first signal transmission line utilizing a frequency divider circuit.

Abstract: Computer-implemented methods for performing enhanced resolution time-domain reflectometry are provided. Aspects include obtaining a plurality of waveforms by transmitting a first pulse on a transmission line, transmitting a second pulse on the transmission line, where the second pulse is transmitted after the first pulse by a delay, and capturing and measuring reflections of the transmitted pulses, wherein the delay corresponding to each of the plurality of waveforms is different. Aspects also include identifying a discontinuity of the transmission line based at least in part on the plurality of waveforms. Based on a determination that the transmission line includes the discontinuity, aspects include calculating third derivative curves for each of the plurality of waveforms and calculating a length of the discontinuity of the transmission line based on the third derivative curves. Aspects also include creating a notification indicating a location and the length of the discontinuity of the transmission line.

Abstract: A method, computer system, and a computer program product for computer memory structural analysis are provided. A processor receives test results that indicate baseline interface voltage level that is from a transient data transmission and is measured at the computer memory. In response to detecting, via the processor, that the test results indicate a baseline wander for the baseline interface voltage level of the computer memory, the processor generates, based on the baseline wander, an identification of an associated structural communication flaw of the computer memory and a compensation recommendation for compensative for the structural flaw. The processor transmits the compensation recommendation for presentation of the compensation recommendation.
