Zenith Electronics

Zenith Electronics is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Zenith Electronics rather than just read about it. In short: Zenith Electronics, LLC is an American research and development company that develops ATSC and digital rights management technologies. It is owned by the South Korean company LG Electronics.

Key takeaways

Zenith Electronics belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Zenith Electronics to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Zenith Electronics from memory before moving on to harder problems.

Reference excerpt

Zenith Electronics, LLC is an American research and development company that develops ATSC and digital rights management technologies. It is owned by the South Korean company LG Electronics. Zenith was previously a brand of consumer electronics, a manufacturer of radio and television receivers and other consumer electronics. For many years, its famous slogan was "The quality goes in before the name goes on." Zenith was the inventor of subscription television and the modern remote control, and was the first to develop high-definition television (HDTV) in North America. Previously headquartered in Glenview, Illinois, after a series of layoffs, the consolidated headquarters moved to Lincolnshire, Illinois. LG Electronics acquired a controlling share of Zenith in 1995; Zenith became a wholly owned subsidiary in 1999. Zenith-branded products were sold in North America, Germany, Thailand (until 1983), Cambodia, Laos, Vietnam, India, and Myanmar.

History

The company was co-founded by Ralph Matthews and Karl Hassel in Chicago, Illinois, as Chicago Radio Labs in 1918 as a small producer of amateur radio equipment. The name "Zenith" came from ZN'th, a contraction of its founders' ham radio call sign, 9ZN, and Zenith having the established meaning of the highest point reached by a given celestial object, or a time of success and notability. They were joined in 1921 by Eugene F. McDonald, and Zenith Radio Company was incorporated in 1923. The fledgling company soon became known for its high-quality radios and electronic innovations. Zenith introduced the first portable radio in 1924, the first mass-produced AC radio in 1926, and push-button tuning in 1927. It added automobile radios in the 1930s with its Model 460, promoting the fact that it needed no separate generator or battery, selling at US$59.95. The first Zenith television set appeared in 1939, with its first commercial sets sold to the public in 1948. The company is credited with having invented such things as the wireless remote control and FM multiplex stereo. For many years Zenith used the slogan "the quality goes in before the name goes on". This phrase was used by the Geo. P. Bent Piano Company of Chicago as early as 1906. Zenith established one of the first FM stations in the country in 1940 (Chicago's WWZR, later called WEFM, named for Zenith executive Eugene F. McDonald), which was among the earliest FM multiplex stereo stations, first broadcasting in stereo in June 1961. The station was sold in the early 1970s and is now WUSN.

Worked examples

Example 1 — a first encounter with Zenith Electronics

Start with the simplest possible case. Write down what Zenith Electronics claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Zenith Electronics before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Zenith Electronics ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Zenith Electronics

In research: Zenith Electronics appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Zenith Electronics in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Zenith Electronics is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1918 establishments in Illinois, 1995 mergers and acquisitions, Amateur radio companies, so understanding it makes those chapters shorter.
In everyday life: Look for Zenith Electronics outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
