These can be implemented as analog circuits ( for instance, using a Sallen Key filter topology, a type of active filter ), or as algorithms in digital signal processing systems.

* A unity gain Sallen – Key filter topology with equivalent capacitors and equivalent resistors is critically damped ( i. e., ).

An example of high-pass active filter of the Sallen – Key topology | Sallen – Key electronic filter topology | topology.

The Sallen – Key topology is an electronic filter topology used to implement second-order active filters that is particularly valued for its simplicity.

A Sallen – Key filter is a variation on a VCVS filter that uses a unity-gain amplifier ( i. e., a pure buffer amplifier with 0 dB gain ).

Implementations of Sallen – Key filters often use an operational amplifier configured as a voltage follower ; however, emitter or source followers are other common choices for the buffer amplifier.

The generic unity-gain Sallen – Key filter topology implemented with a unity-gain operational amplifier is shown in Figure 1.

Figure 1: The generic Sallen – Key filter topology.

This interpretation is the reason why Sallen – Key filters are often drawn with the operational amplifier's non-inverting input below the inverting input, thus emphasizing the similarity between the output and ground.

Figure 3: A low-pass filter, which is implemented with a Sallen – Key topology, with f < sub > c </ sub >= 15. 9 kHz and Q = 0. 5.

Figure 4: A specific Sallen – Key high-pass filter with f < sub > c </ sub >= 72 Hz and Q = 0. 5.

Although it uses a different topology and an operational amplifier configured to provide non-unity-gain, it can be analyzed using similar methods as with the generic Sallen – Key topology.

In the command centers there are special clocks ready to tick off the minutes elapsed since `` E hour ''.

`` E '' stands for `` execution '' -- the moment a `` go order '' would unleash an American nuclear strike.

Meaningful policies include: ( A ) kinds of cars the state should own, ( B ) when cars should be traded, ( C ) the need and assignment of vehicles, ( D ) use of cars in lieu of mileage allowances, ( E ) employees taking cars home, and ( F ) need for liability insurance on state automobiles.

The first one or two roof boards ( marked `` E '' in fig. 6 ) are slipped into place across the roof beams, from outside the shelter.

For United States expenditures under subsections ( A ), ( B ), ( D ), ( E ), ( F ), ( H ) through ( R ) of Section 104 of the Act or under any of such subsections, the rupee equivalent of $200 million.

For grant to the Government of India under subsection ( E ) of Section 104 of the Act, the rupee equivalent of not more than $538 million for financing such projects to promote balanced economic development as may from time to time be mutually agreed.

The rupee equivalent of $63.8 million, but not more than 5 percent of the currencies received under the Agreement will be used for loans to be made by the Export-Import Bank of Washington under Section 104 ( E ) of the Agricultural Trade Development and Assistance Act, as amended ( hereinafter referred to as the Act ), and for administrative expenses of the Export-Import Bank of Washington in India incident thereto.

Such loans under Section 104 ( E ) of the Act will be made to United States business firms and branches, subsidiaries, or affiliates of such firms in India for business development and trade expansion in India and to United States firms and to Indian firms for the establishment of facilities for aiding in the utilization, distribution, or otherwise increasing the consumption of and markets for United States agricultural products.

In the event the rupees set aside for loans under Section 104 ( E ) of the Act are not advanced within six years from the date of this Agreement because the Export-Import Bank of Washington has not approved loans or because proposed loans have not been mutually agreeable to the Export-Import Bank of Washington and the Department of Economic Affairs of the Government of India, the Government of the United States of America may use the rupees for any purpose authorized by Section 104 of the Act.

With respect to Article 2,, paragraphs 1 ( B ) and 1 ( C ): Uses of Section 104 ( E ) and Section 104 ( G ) rupees: The Government of India will use the amount of rupees granted or loaned to it by the United States pursuant to paragraphs 1 ( B ) and 1 ( C ) for projects to promote economic development with emphasis upon the agricultural sector including food reserve storage structures and facilities as may from time to time be agreed upon by the authorized representatives of the United States and the authorized representatives of the Government of India, in the following sectors: A.

Other economic development projects consistent with the purposes of Sections 104 ( E ) and 104 ( G ) of the Act.

Aside from this, the average portion contains some protein, an appreciable amount of vitamins A and C -- about one-tenth of the minimum daily requirement, and about a third of the official vitamin E requirement.

Thus if E is sufficiently small, there can be only one intersection of C and Af near Q, for if there were more than one intersection for every E then the difference between C and Af near Q would not be a monotone function.
