* The filter should be stable

A stable filter assures that every limited input signal produces a limited filter response.

Due to the high filter order that can be achieved in an easy and stable manner, single chip analog sampled filters are often used for implementing anti-aliasing filters for digital filters.

This is in contrast to the FIR filter where all poles are located at the origin, and is therefore always stable.

ARP Instruments made a multifunction voltage-controlled filter module capable of stable operation at a Q greater than 100 ; it could be shock-excited to ring like a vibraphone bar.

This stable network acts as a filter, trapping large particles of fat or protein, while allowing water and smaller, flavor-active compounds to pass.

However, an optimal Kalman filter is probably stable only if Kalman's observability and controllability conditions are also satisfied ( Kalman, 1960 ).

The straight column under load is in stable equilibrium if a lateral force, applied between the two ends of the column, produces a small lateral deflection which disappears and the column returns to its straight form when the lateral force is removed.

The iamb, for example, is the most natural form of rhythm in the English language, and generally produces a subtle but stable verse.

This produces a stable, minimum energy configuration in which the outer electrons are tightly bound.

The quasiequilibrium produces radioactive isobars < sup > 44 </ sup > Ti, < sup > 48 </ sup > Cr, < sup > 52 </ sup > Fe, and < sup > 56 </ sup > Ni, which ( save < sup > 44 </ sup > Ti ) are created in such abundance as to decay after the explosion to create the most abundant stable isotope of the corresponding element at the same atomic weight.

This produces a stable, minimum energy configuration in which the outer electrons are tightly bound.

Designed so that a load produces a rotational force, the logarithmic cam shape allowed for a single device to fit in a range of crack sizes without a change in the loading pattern, making it predictable and stable.

This observation reinforces the idea that social origin, more than economic capital, produces aesthetic preferences because regardless of economic capability consumption patterns remain stable.

This process produces stable isotopes by moving along the valley of beta-decay stable isobars in the chart of isotopes.

The rule that excess electrons in the ring produces an exceptionally stable (" aromatic ") compound, is known as the Hückel's rule.

Crosses between a male Green Peafowl, Pavo muticus and a peahen produces a stable hybrid called a " spalding ", named after Mrs. Keith Spalding, a bird fancier in California.

For thinking cannot therefore be solely a producer of thoughts alone to Gentile, as is the position taken by materialists, because thoughts are to him what negate it, but must also be what produces the stable environment wherein being happens.

It produces a heat stable toxin enterotoxin when allowed to grow for several hours in foods such as cream-filled baked goods, poultry meat, gravies, eggs and meat salads, puddings and vegetables.

The attack on the carbon produces a more stable compound than direct attack.

Irradiation of natural tellurium produces almost entirely I-131 as the only radionuclide with a half-life longer than hours, since most lighter isotopes of tellurium become heavier stable isotopes, or else stable iodine or xenon.

Disposal of Cs-135 by nuclear transmutation is difficult, because of the low cross section as well as because neutron irradiation of mixed-isotope fission caesium produces more Cs-135 from stable Cs-133.

Ringing refers to an output variation that cycles above and below an amplifier's final value and leads to a delay in reaching a stable output.

A linear system that takes an input is called bounded-input bounded-output ( BIBO ) stable if its output will stay bounded for any bounded input.

Their high yield converts into superior energy resolution ; moreover, the light output is very stable and quite high over a very wide range of temperatures, making it particularly attractive for high temperature applications.

Most implementations produce a stable sort, which means that the implementation preserves the input order of equal elements in the sorted output.

# using a stable optical source, at the wavelength of interest, to drive a mode scrambler, the output of which overfills ( drives ) a 1 to 2 meter long reference fiber having physical and optical characteristics matching those of the fiber under test,

Stable angina is due to inability to supply the myocardium ( heart muscle ) with sufficient blood in situations of increased cardiac output ( such as exertion ), and this pain of stable angina normally resolves with rest or nitroglicerin ( sublingual spray or tablet ).

) In some simple New Keynesian DSGE models, it turns out that stabilizing inflation suffices, because maintaining perfectly stable inflation also stabilizes output and employment to the maximum degree desirable.

In this circuit, a typical voltage reference or regulator, an input voltage, U < sub > IN </ sub >, is regulated down to a stable output voltage U < sub > OUT </ sub >.

Because of the application to radix sorting, it is important for counting sort to be a stable sort: if two items have the same key as each other, they should have the same relative position in the output as they did in the input.

The factory management would often create the Stakhanovite brigades or departments, which reached a stable higher collective output.

* How stable its output voltage or current is under varying line and load conditions.

The productive output of the Matrix is based upon this repeated cycle of destruction and recreation, to keep the human minds which power it in a stable structure.

* United States – Mixed policy dedicated to maximum employment and stable prices ( and since the 1980s it is well described by the " Taylor rule ," which maintains that the Fed funds rate responds to shocks in inflation and output )

Prior to the 1980's, Marche was considered a rather poor region, although economically stable in some sectors, thanks particularly to its agricultural output and to the contribution of traditional crafts.

When these conditions are met for one or more longitudinal modes then radiation in those modes will rapidly build up until gain saturation occurs, resulting in a stable continuous laser beam output through the front ( typically 99 % reflecting ) mirror.

To obtain a reasonably stable output voltage the output current should be a small fraction of the input current.

The original MFP model ( Solow 1957 ) involves several assumptions: that there is a stable functional relation between inputs and output at the economy-wide level of aggregation, that this function has neoclassical smoothness and curvature properties, that inputs are paid the value of their marginal product, that the function exhibits constant returns to scale, and that technical change has the Hicks ’ n neutral form ( Hulten, 2009, 5 ).

When a network is in such a condition, it has settled ( under overload ) into a stable state where traffic demand is high but little useful throughput is available, and there are high levels of packet delay and loss ( caused by routers discarding packets because their output queues are too full ) and general quality of service is extremely poor.

FIR filters are clearly bounded-input bounded-output ( BIBO ) stable, since the output is a sum of a finite number of finite multiples of the input values, so can be no greater than times the largest value appearing in the input.

They are both very hygroscopic ( i. e., damaged when exposed to moisture in the air ) but offer excellent light output and energy resolution ( 63 photons / keV γ for LaBr < sub > 3 </ sub >( Ce ) versus 38 photons / keV γ for NaI ( Tl )), a fast response ( 16 ns for LaBr < sub > 3 </ sub >( Ce ) versus 230 ns for NaI ( Tl )), excellent linearity, and a very stable light output over a wide range of temperatures.

Moreover, the light output is very stable and quite high over a very wide range of temperatures, making it particularly attractive for high temperature applications.
