Digital/analogue converter
proportional DC voltage. In conjunction with digitised signal processing provided by microelectronics, D/A converters are required to be able to control analogue control elements ( continuously adjustable valves
Digital setpoint control
signal processing . This statement also applies if the control circuit is analogue, above all if a D/A converter is used (pre-loop processing).
Sampling control circuit
the control algorithm , this new correcting variable is then supplied to the holding circuit (mostly D/A converters). This correcting variable is then available on the microcomputer's output until the next
