Field-programmable gate arrays (FPGAs), chips with logic circuitry whose configuration can be modified after fabrication, are also widely used in prototyping and development.. This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Field-programmable gate arrays (FPGAs), chips with logic circuitry whose configuration can be modified after fabrication, are also widely used in prototyping and development.. resistors, diodes, inductors and capacitors). In digital electronic circuits, electric signals take on discrete values, to represent logical and numeric values.[3] These values represent the information that is being processed. The ability of electronic devices to act as switches makes digital information processing possible. Wires are usually treated as ideal zero-voltage interconnections; any resistance or reactance is captured by explicitly adding a parasitic element, such as a discrete resistor or inductor. Analog circuitry is constructed from two fundamental building blocks: series and parallel circuits. The website 'The High Tech Society' focusing on recent tech news and developments as well as game and gadget reviews could also be referred to as the high tech society. Digital circuitry is used to create general purpose computing chips, such as microprocessors, and custom-designed logic circuits, known as application-specific integrated circuit (ASICs).
