摘要
A teaching aid has outputs for a number of listening points with switches for the listeners and for the control position. It uses a screen. Between them is a logic control system with an equaliser and memory arrangement. This has a switching system in series with the equalisers for the listening positions so that they can be connected in sequence. The data input section at the control position has an equaliser input with a switching system which connects the memories in sequence. These memories can be connected by push-buttons to the teaching aid. The logic system has a set of evaluator channels in parallel, each with a classifier circuit, several counters and a memory. One of the evaluators is connected to a percentage calculator.
