I report on special features of a course on statistics and probabilities at my university, where future teachers of mathematics in primary school are instructed on en-active representations of statistical situations and on their analogue modelling. I also report on empirical work with future mathematics teachers of primary school in Baden Württemberg who have been instructed to introduce simple...

The basic properties of programmable analogue arrays are described and the problem of quantifying the fitness of an analogue circuit is discussed. A set of blocks appropriate for use in an evolutionary algorithm is described and results presented showing how an evolutionary algorithm using these blocks can learn to produce a given input-output characteristic. Finally an example is presented sho...

A new method is proposed in this paper for multiple fault diagnosis in linear analog circuits. The test equation in the traditional large change sensitivity method is modified to establish the linear relationship between the measurements and the faulty parameter deviations with the coefficient matrix derived from the nominal values of circuit parameters. By using a recently developed method to ...

A new time-interleaved noise-shaping quantiser architecture is proposed. By employing a time-interleaving technique with a new path-coupling scheme, higher order of noise shaping and increased bandwidth are achieved. This general topology can be employed to synthesise any noise transfer function without the need for dedicated digital-to-analogue converters to extract the quantisation noise. Sim...

| We describe a connectionist architecture which shows promise in obtaining the global optimal solution to the classical minimum spanning tree problem in a time independent of the problem size. Using commonly available analogue electronic components, a network prototype was found to give the global optimal solution within the microseconds range. Simulation results and limiting factors of the pe...
