RCA Electronic Music is the first synthesizer prior to the creation of artificial electronic sounds. 1952 Reintroduction of regular television broadcasts in Germany after the Second World War. 20th Century Fox developed with "Cinemascope" the most successful wide-screen process to better compete with television. Only some 50 years later pulls ...
Many electronics engineers today specialize in the development and programming of microprocessor-based electronic systems, known as embedded systems. Hybrid specializations such as computer engineering have emerged due to the detailed knowledge of the hardware that is required for working on such systems. [41]
Printed circuit board Electrical Circuit with an IC.. Electronic engineering is a sub-discipline of electrical engineering that emerged in the early 20th century and is distinguished by the additional use of active components such as semiconductor devices to amplify and control electric current flow.
These systems were replaced by cheaper and more versatile electrical systems, but by the end of the 19th century, city planners and financiers were well aware of the benefits, economics, and process of establishing power transmission systems. In the early days of electric power usage, widespread transmission of electric power had two obstacles ...
Electromagnets were then used in the first practical engineering application of electricity by William Fothergill Cooke and Charles Wheatstone who co-developed a telegraph system that used a number of needles on a board which were moved to point to letters of the alphabet. A five needle system was used initially, but was given up as too expensive.
The world's first all-electronic desktop calculator was the British Bell Punch ANITA, released in 1961. [38] [39] It used vacuum tubes, cold-cathode tubes and Dekatrons in its circuits, with 12 cold-cathode "Nixie" tubes for its display. The ANITA sold well since it was the only electronic desktop calculator available, and was silent and quick.

The first planar monolithic integrated circuit (IC) chip was demonstrated in 1960. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic ...
