In the Indian education system of some Indian states, the Pre-University Course (PUC) or Pre-Degree Course (PDC) is referred to as intermediate or +2 course, which is a two-year senior secondary education course that succeeds the tenth grade (known as SSLC or SSC in such states, equivalent to sophomore in the US system) and precedes to the completion of a Senior Secondary Course.
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 ...
First commercial sound films ("The Jazz Singer", USA) using the "Needle sound" back in sync with the film screening for LPs over loudspeakers. First public television broadcasts in the UK by John Logie Baird between London and Glasgow and in the US by Frederic Eugene Ives (1882–1953) between Washington and New York.
Principles of Electronics is a 2002 book by Colin Simpson designed to accompany the Electronics Technician distance education program and contains a concise and practical overview of the basic principles, including theorems, circuit behavior and problem-solving procedures of Electronic circuits and devices.
The first integrated circuit logic gates cost nearly US$50, which in 2023 would be equivalent to $515. Mass-produced gates on integrated circuits became the least-expensive method to construct digital logic. With the rise of integrated circuits, reducing the absolute number of chips used represented another way to save costs. The goal of a ...
The electronics industry consists of various sectors. The central driving force behind the entire electronics industry is the semiconductor industry sector, [33] which has annual sales of over $481 billion as of 2018. [34] The largest industry sector is e-commerce, which generated over $29 trillion in 2017. [35]
Government Engineering College, Barton Hill (GEC-BH) is a public engineering college situated in Barton Hill, Thiruvananthapuram, India.Founded in 1999 by the Government of Kerala, it provides engineering programmes under the APJ Abdul Kalam Technological University, accredited to the National Board of Accreditation.
Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves . In modern systems, the conversion is performed with semiconductor switching devices such as diodes , thyristors , and power transistors such as the power MOSFET and IGBT .
