A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The amount of attenuation for each frequency depends on the filter design. A high-pass filter is usually modeled as a linear time-invariant system.
Cut off period. Cutoff period is a term in finance. In capital budgeting, it is the period (usually in years) below which a project's payback period must fall in order to accept the project. Generally it is the time period in which a project gives its investment back if a project fails to do so the project will be rejected. For example, a ...
A material take off (MTO) is the process of analyzing the drawings and determining all the materials required to accomplish the design. Thereafter, the material take off is used to create a bill of materials (BOM). Procurement and requisition are activities that occur after the bill of materials is complete, distinct from Inspection.
The cutoff frequency is the critical frequency between propagation and attenuation, which corresponds to the frequency at which the longitudinal wavenumber is zero. It is given by The wave equations are also valid below the cutoff frequency, where the longitudinal wave number is imaginary. In this case, the field decays exponentially along the ...
Cutoff (physics) In theoretical physics, cutoff (AE: cutoff, BE: cut-off) is an arbitrary maximal or minimal value of energy, momentum, or length, used in order that objects with larger or smaller values than these physical quantities are ignored in some calculation. It is usually represented within a particular energy or length scale, such as ...
Cutoff (metalworking), a piercing operation used to cut a workpiece from the stock. Cutoff (meteorology), a high- or low-pressure system stuck in place due to a lack of steering currents. Cutoff (physics), a threshold value for a quantity. Cutoff (reference value), a one-sided reference range in health-related fields.
In electronics, cut-off is a state of negligible conduction that is a property of several types of electronic components when a control parameter (that usually is a well-defined voltage or electric current, but could also be an incident light intensity or a magnetic field ), is lowered or increased past a value (the conduction threshold).
Cut-off factor (AKA " cut-off length ") is a factor used to calculate the length of a hose cut to achieve the desired overall length of hose plus fittings. It is commonly seen in hydraulic hose and fitting specifications. The cut-off factor is specific to a particular hose fitting. The formula used in calculating the optimum overall length is ...
