The paper considers the design of the equalizer and the desired overall system impulse response (d. i. r. ) for various types of detection algorithms used to recover digital data which has suffered intersymbol interference. The joint optimization of the equalizer and desired response is formulated using a mean-square error cost. A constraint on the desired response is introduced which enables simple adaptive algorithms to be derived for determining the optimum equalizer and d. i. r. One of the algorithms considered has been found to converge rapidly and is thus ideally suited for application where fast start-up is required. Simulation results of the probability of error performance of various detection algorithms using the equalizer and d. i. r. designed according to the approach developed in the paper, are presented. These results show that the performance obtained is comparable to that achieved with systems in which the equalizer and d. i. r. are designed according to other techniques. The disadvantage of these other techniques is that they usually lead to algorithms which are difficult to make adaptive and are slow to converge.

This paper reports a stage of a project (tertiary education in applied mathematics, TEAM) aimed at investigating aspects of first-year undergraduate mathematics courses. The aims of this part of the project are to provide information about first-year students' expectations and preferences, and a general view of lecturers' aims in relation to such courses. © Taylor & Francis Group, LLC.

A method is developed for locating regions of the Burmester circle-point curve which give the driving cranks of crank-rocker or drag-link linkages when combined with a given driven crank. The technique used is a graphical iteration procedure. When used as suggested convergence is rapid. The technique is compatible with the author's procedure for avoiding solutions requiring branch changes and ensuring correct order of progression through the design positions. © 1978.

A method is presented to resolve the ambiguity in Waldron's solution to the order problem of planar Burmester synthesis by inspection of an image pole circle. This replaces the more cumbersome method previously used. Another method is presented to allow the mapping of permissible segments of the circle-point curve, in Waldron's solution to the branch problem by inspection of the subscripts of the Qij, Tij and Uij points. This replaces the much more cumbersome angle sign table previously used. © 1978.
