Output Waveforms
multiple sets photodetectors signal processing circuitry necessary produce digital waveforms. codewheel/codestrip passes between emitter detector, causing light beam interrupted pattern spaces bars codewheel. photodiodes which detect these interruptions arranged pattern that corresponds codewheel/ codestrip. These detectors also spaced such that light period pair detectors corresponds dark period adjacent pair detectors. photodiode outputs then through signal processing circuitry resulting Comparators receive these signals produce final outputs channels this integrated phasing technique, digital output channel quadrature with

Count (N): number window pairs counts revolution (CPR) codewheel. cycle (C): electrical degrees (°e), window pair. Shaft Rotation: mechanical degrees, cycles. Pulse Width (P): number electrical degrees that output high during cycle. This value nominally 180°e cycle. Pulse Width Error deviation, electrical degrees pulse width from ideal value 180°e. State Width (S): number electrical degrees between transition output channel neighboring transition output channel There states cycle, each nominally 90°e.
