Frequency response is defined as: A measure of the effectiveness with which a circuit, device, or system transmits the different frequencies applied to it. It is a phasor whose magnitude is the ratio ...

Negative-stiffness mechanical isolators can be used for achieving high-performance vibration isolation in a small microscope platform. It can be challenging to use microscopy for imaging materials, ...

A variable frequency driven (VFD) is a type of motor that controls the levels of frequency and voltage that alter the speed of an electric motor. The drive alters torque and motor speed and can be ...
