Alberta is one of the thirteen provinces and territories of Canada. It is a part of Western Canada and is one of the three prairie provinces. Alberta borders British Columbia to the west, Saskatchewan to the east, the Northwest Territories to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada, with Saskatchewan being the other. The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds.
AB, Ab, or ab may refer to:
A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s. Valve amplifiers can be used for applications such as guitar amplifiers, satellite transponders such as DirecTV and GPS, high quality stereo amplifiers, military applications and very high power radio and UHF television transmitters.
Beaumont is a city in Leduc County within the Edmonton Metropolitan Region of Alberta, Canada. It is located at the intersection of Highway 625 and Highway 814, adjacent to the City of Edmonton and 6.0 kilometres (3.7 mi) northeast of the City of Leduc. The Nisku Industrial Park and the Edmonton International Airport are located 4.0 kilometres (2.5 mi) to the west and 8.0 kilometres (5.0 mi) to the southwest respectively.
A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier, some of which have output power measured in kilowatts, and are used in amateur radio. Other types of linear amplifier are used in audio and laboratory equipment. Linearity refers to the ability of the amplifier to produce signals that are accurate copies of the input. A linear amplifier responds to different frequency components independently, and tends not to generate harmonic distortion or intermodulation distortion. No amplifier can provide perfect linearity however, because the amplifying devices—transistors or vacuum tubes—follow nonlinear transfer function and rely on circuitry techniques to reduce those effects. There are a number of amplifier classes providing various trade-offs between implementation cost, efficiency, and signal accuracy.
The EL34 is a thermionic vacuum tube of the power pentode type. The EL34 was introduced in 1955 by Mullard, who were owned by Philips. The EL34 has an octal base and is found mainly in the final output stages of audio amplification circuits; it was also designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters. The American RETMA tube designation number for this tube is 6CA7. The USSR analog was 6P27S.
Nanton is a town in southern Alberta, Canada. Nanton was named after Sir Augustus Meredith Nanton of Winnipeg (1860–1925) who directed firms which offered financing for farms and ranches throughout the west. It is located south of Calgary at the junction of Highway 2 and Highway 533.
Alberta Provincial Highway No. 26, commonly referred to as Highway 26, is an east–west highway in central Alberta, Canada that connects Highway 13 in Camrose to Highway 14 near Kinsella. The route follows 12th Correction Line for its entire length, and does not pass through any communities east of Camrose.
A valve audio amplifier (UK) or vacuum tube audio amplifier (US) is a valve amplifier used for sound reinforcement, sound recording and reproduction.
Cypress County is a municipal district in southeastern Alberta, Canada that surrounds the City of Medicine Hat and the Town of Redcliff. The municipality is part of Census Division 1, Alberta. The first farm in the area was settled in 1890.
The KT88 is a beam tetrode/kinkless tetrode vacuum tube for audio amplification.
AB1(formally AB Channel 1 until 1995) is a French television channel aimed at young adults.
The AB postcode area, also known as the Aberdeen postcode area is a group of 33 postcode districts in north-east Scotland, within 24 post towns. These cover the Aberdeen council area, Aberdeenshire and east Moray.
Technical specifications and detailed information on the valve audio amplifier, including its development history.
AB Sat is a package of digital terrestrial television channels offered by the satellite companies Hot Bird and Astra and marketed in France, Belgium, Switzerland and Germany. The channels are all run by the cable operators and certain networks ADSL. ABSAT has a stake on two digital terrestrial television channels. The company is chaired by Michele Cotta.
Tube sound is the characteristic sound associated with a vacuum tube amplifier, a vacuum tube-based audio amplifier. At first, the concept of tube sound did not exist, because practically all electronic amplification of audio signals was done with vacuum tubes and other comparable methods were not known or used. After introduction of solid state amplifiers, tube sound appeared as the logical complement of transistor sound, which had some negative connotations due to crossover distortion in early transistor amplifiers. However, solid state amplifiers have been developed to be flawless and the sound is later regarded neutral compared to tube amplifiers. Thus the tube sound now means 'euphonic distortion.' The audible significance of tube amplification on audio signals is a subject of continuing debate among audio enthusiasts.
Campsie is a hamlet in central Alberta within the County of Barrhead No. 11, located approximately 17 kilometres (11 mi) west of Barrhead then 1 kilometre (0.62 mi) north of Highway 18, roughly 101 kilometres (63 mi) northwest of Edmonton. It has an elevation of 660 m (2,170 ft).
