Program-controlled generation of measurement signals or control signals

摘要

The invention relates to the use of the video and audio information replay technology operating with laser-optically scanned discs for program-controlled generation of measurement signals or control signals, particularly for calibration purposes, audiometric investigations, measurements in building acoustics, distortion factors and frequency response measurements and in audiometry in the audio frequency range, also for generating arbitrary signal curve forms in the sound frequency range and in the ultrasonic and infrasound range, also for medical purposes, for example for heart stimulation.
