Smoothing a signal
Possible noise elements on a signal are removed or suppressed by a downstream filter . The term smoothing is used if, e.g., by means of the usage of an RC low pass filter the linearity of a signal is
Manual adjustment
Adjustment of the output volume of a pump or the displacement of a motor by hand via a spindle. Once the desired value has been set, the pump/motor continues to work as a fixed displacement unit.
Hand pump
Hydraulic pump — mostly with a single piston — for manual operation. It is single-acting in most cases, i.e. priming occurs during the first section of the cycle and delivery during the second. With d
Hamming distance d
Term used in digital signal transmission, signal processing ; measure of the resilience of a code against transmission errors (literature: R. W. Hamming, Error Detecting and Error Correcting Codes, Be
Holding current
Minimum current needed to flow in an electrical load circuit (e.g. in a solenoid or another electro-mechanical signal converter) in order for a valve to be held in the closed position by the electro-m
Holding element
Retains the instantaneous value for an input signal recorded by a sampler as the output signal until the next sampling (DIN 19 226).
Digital control with signal hold
In a digital control with signal hold, the value achieved for the output variable is retained following removal or withdrawal of the reference variable — particularly following termination of the trig
Hall effect sensor
Contactless electrical switch for detecting positions using the Hall effect: if a current-carrying conductor is exposed to a magnetic field, a "Hall voltage" is generated in the conductor, which — dul
Half open hydraulic circuit
If the principle of the closed circuit is applied to a differential cylinder , the fact that different areas are involved means suction must also take place from the container when switching to feed m
Semiconductor memory
Static RAM, SRAM : The storage cells consist of bistable circuitry elements with a functionality similar to that of a flip-flop. The information is not volatile; it is stored until the storage element
