  23. PROJECTS IN ELECTRONICS ENGINEERING Kit based Projects: • LED Based Water Level indicator • FM Receiver • Intercom 2 Way • Digital Clock Tele Based Projects: • Telephone call recorder • Tele based Home security • Optical Fiber based Data Communication • VLSI Based Projects

  24. TRENDS IN ELECTRONICS ENGINEERING • The basic principle of operation of thermionic diodes was discovered by Frederick Guthrie in 1873 • In 1904, the vacuum-tube diode was introduced by J. A. Fleming. • In 1906, Lee De Forest added a third element, called the control grid, to the vacuum diode, resulting in the first amplifier, the triode. • In1930s the four-element tetrode and five-element pentode gained • prominence in the electron-tube industry. • 5. On December 23, 1947, Walter H. Brattain and John Bardeen • demonstrated the amplifying action of the first transistor at the Bell • Telephone Laboratories. 6. Drs. Ian Munro Ross (front) and G. C. Dacey jointly developed an experimental procedure for measuring the characteristics of a field-effect transistor in 1955.

  25. Trends….. continued 7. An op-amp is first found in US Patent 2,401,779 "Summing Amplifier" filed by Karl D. Swartzel Jr. of Bell labs in 1941. 8. The popularity of monolithic op-amps was further improved upon the release of the LM101 in 1967, which solved a variety of issues, and the subsequent release of the μA741 in 1968.
