background: multiple choice tests (mct), are widely known and applied as useful evaluation tests in the field of education especially in medical science. items on a multiple-choice test consist of a stem, which is followed by a correct answer as well as three to four distracters. items on a well-written multiple-choice test will have stems that are precise and clear, one answer that is clearly ...

We report on a novel data acquisition system, as part of a project to measure feedbackcoupled ERP signals, which uses wavelet transformation to decompose EEG signals in realtime in their respective energy bands. Due to constraints in DSP-based computing power, we have to settle for the less than optimal decomposition by short wavelets, but nevertheless achieve satisfactory discrimination power ...
