ABSTRACT:
A digital position signal generator suitable for gain control and other purposes. A typical embodiment includes a rotary disk notionally divided into a plurality of sectors of the same angle about the disk axis. Some of the disk sectors have radial extensions which are detectable by photocouplers. The photocouplers are fixedly disposed about the disk axis with angular spacings each greater than the angle of each disk sector. Thus, with the rotation of the disk, the photocouplers produce binary zero and one outputs in various predetermined combinations nonsequentially representing successive predetermined angular positions of the disk. A position data generator circuit such as a microcomputer is provided which has stored thereon meaningful position data sequentially representing the successive predetermined angular positions of the disk. Inputting each output combination of the detectors, the position data generator circuit puts out a corresponding one of the meaningful position data. Several other embodiments are disclosed.
