with auxiliary energy, which amplifies the power. Example: Pneumatic pressure amplifier, electrical amplifier, for example with a signal voltage at the input and a signal current at the output with a

Sum of all manipulations required to trigger certain functions in the process (in the system) using defined input signals (DIN 19 237). A distinction is made between analogue , digital and binary sign

Collective term for all measures, procedures and devices, which are required to use given input signals to obtain the necessary for the process by way of suitable signal processing . This applies to t

Ratio of the value of an overlaid interfering signal to the value of the useful signal.

Processor with a reduced instruction set, which is specifically designed to rapidly process signals as required for arithmetic tasks. Signal processors are therefore used for rapid solutions of the Fo

The parameter of a signal , which carries the information. For example, the voltage is the signal parameter in the case of a continuous DC voltage. In the case of a frequency modulated AC voltage sign

Period of time, after which an reacts to a signal change at the corresponding input according to its function (DIN 19 237).

Device to deliver signals which change over time in the form of adjustable voltages with a sinusoidal, rectangular or triangular form, amongst others. Signal generators with computer-assisted, program

Signals may have an analogue, digital or binary character. In addition, they may have a continuous value, i.e. the signal parameter can take on all values within an interval; have a discrete value, i.

Jamming or blocking of the piston caused by a build-up of particles.
