It is the ratio between two frequencies, the frequency at a specified attenuation on the roll-off curve to the corner frequency at its specified attenuation, usually -3dB.
The ratio of the area of an elastomer body subjected to a compressive load to the sum of the areas which are free to bulge. As the shape factor increases, the strain produced by given stress decreases. This is a critical consideration in avoiding heat build-up in dynamic applications. It is also important in static load bearing applications such as structural bearing pads where compressive stress relaxation versus time is to be avoided.
A ratio of two bandwidths. Typically, a comparison of the passband of a filter to its stopband. In bandpass filters, it is the stopband bandwidth divided by the passband bandwidth.
The ratio between two frequencies - the frequency at a specified attenuation on the roll-off curve to the CORNER FREQUENCY at its specified attenuation, usually 3 dB or the mathematical corner frequency depending on the filter type.
the ratio of the area of one load face to the combined area of those surfaces free to expand laterally when a rubber is under compression.
An important parameter of all filters: BANDPASS: SF = Attenuation Bandwidth / 3dB Bandwidth BANDSTOP: SF = 3dB Bandwidth / Attenuation Bandwidth LOWPASS: SF = Attenuation Frequency / Fco HIGHPASS: SF = Fco / Attenuation BandwidthSOURCE
the ratio of one load bearing surface of a rubber part to the combined area of all unloaded surfaces free to expand sideways when the part is subjected to a compressive force; an important characteristic for engineered parts
(Bandwidth Ratio): In a filter, the ratio comparing the high-attenuation level bandwidth and low attenuation level bandwidth. Or the ratio of the 3dB bandwidth to the stopband bandwidth.
