Frequency-voltage converter / signal converter

Frequency-voltage converters are utilized to convert output signals from incremental encoders in a speed-proportional and direction-of-rotation dependent DC voltage or rather direct current. The final speed and pulse rate are set via four coding switches respectively. The resulting value is converted and fed to the analog outputs.
