Abstract

"The expense of developing new circuit designs has forced electronic manufacturers to develop and use multipurpose circuits that can be adapted to fit many requirements. Sometimes this procedure leads to problems that would not have occurred if a circuit, designed to fit a particular application, had been developed. One problem of this type deals with the effect of improperly terminated coaxial cables loading output signals from a digital computer. The unterminated cable reflected the signal back in the computer. This did not affect the putout stage, but the preceeding [sic] driving stage was affected. The degradation of the output of the driving stage affected the entire data flow of the computer and prevented normal operation. The analysis of the circuit is considered using a reflected pulse at the output of the computer, delayed by the length of the cable. During the analysis of the malfunction, the circuit was found to be very susceptable [sic] to shunt capacitance. Since short coaxial cables appear to be capacitive, the effect of capacitance on the circuits is also considered. Several minor circuit changes to alleviate the susceptabiity [sic] of the computer to unterminated coaxial cables and capacitive loads are also considered"--Abstract, page ii.
