Digikey Electronics


Digital circuits are the commonest physical representation of Boolean algebra, and are the idea of all digital computer systems. To most engineers, the phrases “digital circuit”, “digital system” and “logic” are interchangeable within the context of digital circuits. Most digital circuits use a binary system with two voltage ranges labeled “zero” and “1”. Often logic “zero” shall be a decrease voltage and known as “Low” whereas logic “1” is known as “High”.

In April 1955, the IBM 608 was the primary IBM product to make use of transistor circuits with none vacuum tubes and is believed to be the primary all-transistorized calculator to be manufactured for the commercial market. Thomas J. Watson Jr. ordered all future IBM products to use transistors in their design.

However, some methods use the reverse definition (“zero” is “High”) or are present primarily based. Quite typically the logic designer might reverse these definitions from one circuit to the subsequent as he sees match to facilitate his design. Most analog electronic home equipment, such as radio receivers, are constructed from mixtures of a few kinds of primary circuits. Analog circuits use a continuous vary of voltage or current versus discrete levels as in digital circuits. The first working level-contact transistor was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947.

From that time on transistors have been nearly solely used for pc logic and peripherals. However, early junction transistors have been … Read More
