摘要

The rotation or velocity measuring system uses a sensor providing a measuring pulse each time the measured object travels through a given distance. A clock source provides constant frequency clock pulses. The number of measuring pulses within a defined measuring interval and the number of clock pulses within the measuring interval are combined to provide the measured velocity or rotation rate. The clock pulses are recorded by a counter with the counting interval invitiated and terminated by the first and last measuring pulses respectively.
