could not be made any smaller‚ so technology gave us transistors. Transistors were used in computers from 1959 to 1964. One transistor took the place of 40 vacuum tubes. When the limits of the transistor were reached‚ computer builders used integrated circuits from 1965 to 1970. In 1971‚ the microprocessor came

material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor ’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power‚ a transistor can amplify a signal. Today‚ some transistors are packaged individually‚ but many more are found embedded in integrated circuits. Inside a transistor: a BJT (Bipolar Junction Transistor) transistor

Classical computing has been operating using a binary system measured in bits. These bits can have only two states‚ zero and one. These states are used to represent‚ store and process data. The binary architecture has been used in computers since Konrad Zues built the first programmable computer in 1941(CITATION). As computers have become more advanced so has the complexity and magnitude of the problems that they can solve. With the current rate of advancement defined by Moore’s law transistors

the Q of a resonant circuit causes its bandwidth to increase. 3. Good selectivity usually means narrow bandwidth. 4. True. A tuned circuit can provide voltage gain. 5. Cascading tuned circuits cause the selectivity to increase. 6. If the selectivity of a tuned circuit is too sharp‚ the sidebands of the received signal may be attenuated. 7. A tuned circuit has a Q of 100 at its resonant frequency of 500 kHz. Its bandwidth is 5 kHz. 8. A parallel LC tuned circuit has a coil of 3µHz
