Appendix 1 Terminology
1. Pulse
Used to turn voltage (current) On/Off for a short time, and pulse line is of continuous pulses
2. Encoder
Used mainly in subo-detector in order to detect speed and position, whose basic principle is that if infrared ray from LED passes the
slit disk and reaches the light receiving element, analog electric sign is output which will be converted by voltage comparator to digital
sign to be output.

Encoder output is classified into 3 types; A phase, A • B phase and A • B • Z phase.
- A phase: Basic output, signal of pulses is output as many as the number of resolutions for 1 revolution of shaft.
- B phase: Signal with a specific phase difference from A phase, which can detect revolution direction of shaft
- Z phase: 1 pulse is output for 1 revolution of shaft.
That is, they are used to reset external counter or to detect the origin position.
3. Manual Pulse Generator
A device that handle can be rotated by hand to generate pulses. If r direction, forward pulses are generated, and if rotated –
direction, reverse pulses are generated.
4. Increasing Counter
A counter value increases from -2,147,483,648 to 2,147,483,647 (for 32-bit counter).
