Input-transducer errors in binary crosscorrelation experiments. Part 3

The crosscorrelation function between the output of an electrical network excited by an imperfect form j(t) of a pseudorandom binary signal i(t) has been determined for four different forms of j(t). The object of the experiments was to simulate the action of a system input transducer, which, because of its dynamic response, is unable to follow i(t) exactly. The effects of both reversible and nonreversible transition delays (of exponential form) have been examined, the measured results confirming previously reported theoretical expressions. In one of the experimental runs, the interstate transition time ¿ of the signal j(t) was considerably greater than the basic interval ¿t of j(t). Although ¿ is apparently too large for the theory to be applicable in this case, it was found that a reasonably accurate estimate of the measured crosscorrelation functions could nevertheless be made using the theory.
