<strong>LINEPULS</strong><br />
Output circuits<br />
1Vpp output circuit provides s<strong>in</strong>usoidal analogue signals phase-shifted by 90 electrical degrees<br />
(s<strong>in</strong>e and cos<strong>in</strong>e) for external <strong>in</strong>terpolation. S<strong>in</strong>usoidal signals have an amplitude of<br />
typically 0.5 Vpp (peak-to-peak) and a 2.5V offset.<br />
1Vpp output level results from differential signals detection. The frequency of the output<br />
signals is <strong>in</strong> direct ratio to the travel speed of the device.<br />
S<strong>in</strong>usoidal signals can be highly <strong>in</strong>terpolated by the follow<strong>in</strong>g electronics <strong>in</strong> order to <strong>in</strong>crease<br />
the resolution. In this way the transmission frequency along the cable is significantly<br />
reduced.<br />
A (cos<strong>in</strong>e) and B (s<strong>in</strong>e) signals (standard code sequence) plus 0 signal are shown <strong>in</strong> the Figure.<br />
1Vpp s<strong>in</strong>/cos (code V)<br />
Advantages: s<strong>in</strong>usoidal signals can be highly <strong>in</strong>terpolated, thus <strong>in</strong>creas<strong>in</strong>g the resolution<br />
and reduc<strong>in</strong>g the transmission frequency over long cables.<br />
Disadvantages: needs electronics for <strong>in</strong>terpolation.<br />
