WitrynaDescription. This Variable Attenuator DC Block (VATTENDCB) is a one input, one output attenuator that operates with a variable attenuation range that can be user selected via a potentiometer control. This unit provides between 3 – 37dB (typical) of attenuation in a miniaturized housing. The frequency response covers the GPS L1/L2 … Crumple zones, crush zones, or crash zones are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change in velocity (and consequently momentum) occurs from the impact during a collision by a controlled deformation; in recent years, it is also incorporated into trains and railcars. can staring at a screen make you dizzy
