The US Senate is a legislative chamber-Sample Text

♠ Posted by Unknown in America,Wave-Pattern

The United States Senate is a legislative chamber in the bicameral legislature of the United States of America, and together with the U.S. House of Representatives makes up the U.S. Congress. First convened in 1789, the composition and powers of the Senate are established in Article Oneof the U.S. Constitution.

•  Each U.S. state is represented by two senators, regardless of population, who serve staggered six-year terms. 
• The chamber of the United States Senate is located in the north wing of the Capitol, in Washington, D.C., the national capital. 
• The House of Representatives convenes in the south wing of the same building.

The Senate has several exclusive powers not granted to the House

The Senate has several exclusive powers not granted to the House, including consenting to treaties as a precondition to their ratification and consenting to or confirming appointments of Cabinet secretaries, federal judges, other federal executive officials, military officers, regulatory officials, ambassadors, and other federal uniformed officers,as well as trial of federal officials impeached by the House. 

The Senate is both a more deliberative and more prestigious body

The Senate is both a more deliberative and more prestigious body than the House of Representatives, due to its longer terms, smaller size, and statewide constituencies, which historically led to a more collegial and less partisan atmosphere.The Senate is both a more deliberative and more prestigious body than the House of Representatives, due to its longer terms, smaller size, and statewide constituencies, which historically led to a more collegial and less partisan atmosphere.

Waveguide filter electronic filter with waveguide technology

♠ Posted by Unknown in Wave-Pattern

A waveguide filter is an electronic filter that is constructed with waveguide technology. Waveguides are hollow metal tubes inside which anelectromagnetic wave may be transmitted. Filters are devices used to allow signals at some frequencies to pass (the passband), while others are rejected (the stopband). Filters are a basic component of electronic engineering designs and have numerous applications. These include selection ofsignals and limitation of noise. Waveguide filters are most useful in the microwave band of frequencies, where they are a convenient size and have lowloss. Examples of microwave filter use are found in satellite communications, telephone networks, and television broadcasting.

Waveguide filters were developed during World War II

Waveguide filters were developed during World War II to meet the needs of radar and electronic countermeasures, but afterwards soon found civilian applications such as use in microwave links. Much of post-war development was concerned with reducing the bulk and weight of these filters, first by using new analysis techniques that led to elimination of unnecessary components, then by innovations such as dual-mode cavities and novel materials such as ceramic resonators.

Waveguide filter design:

A particular feature of waveguide filter design concerns the mode of transmission. Systems based on pairs of conducting wires and similar technologies have only one mode of transmission. In waveguide systems, any number of modes are possible. problems, and an advantage, as a dual-mode design can be much smaller than the equivalent waveguide single mode design. The chief advantages of waveguide filters over other technologies are their ability to handle high power and their low loss. The chief disadvantages are their bulk and cost when compared with technologies such as microstrip filters.

This can be both a disadvantage, as spurious modes frequently cause problems, and an advantage, as a dual-mode design can be much smaller than the equivalent waveguide single mode design. The chief advantages of waveguide filters over other technologies are their ability to handle high power and their low loss. The chief disadvantages are their bulk and cost when compared with technologies such as microstrip filters.
