A tone control system for use in programming complex experiments is detailed. It utilizes coded tone-pulses recorded on a standard dual-track audio tape recorder. The system provides ten different coded pulses which are detected by a sound operated relay and a pulse steering network. The pulse steering network used to select which of the ten output pulses will appear at any instant is described in detail. A circuit diagram using standard Grason-Stadler relay components is given as is a circuit utilizing standard electronic components. Author
