What is 3db cutoff frequency?
What is 3db cutoff frequency? These cut-off or corner frequency points indicate the frequencies at which the power associated with the output falls to half its maximum value. These half power points corresponds to a fall in gain of 3dB (0.7071) relative to its maximum dB value. What is 3dB bandwidth of a filter? The […]

Why is surface topography important?
Why is surface topography important? Surface topography refers to both the profile shape and the surface roughness (including the waviness and the asperity or the finish). Surface topography affects the film thickness to roughness ratio and the lubrication regime. These interactions become more important as the thickness-to-roughness ratio reduces. What is topography material? The topography […]
