  2. THE ANALOG THING - Wikipedia

    en.wikipedia.org/wiki/THE_ANALOG_THING

    The computer is programmed with patch cables connecting the components on a switching board. It can, additionally, be partly controlled from a digital computer via a hybrid port. If an application requires more computing elements than are available on a single machine, two or more THATs can be coupled via dedicated interfaces referred to as ...

  3. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...

Printed circuit board of a DVD player Part of a 1984 Sinclair ZX Spectrum computer board, a printed circuit board, showing the conductive traces, the through-hole paths to the other surface, and ...

  5. Transistor - Wikipedia

    en.wikipedia.org/wiki/Transistor

    The common-emitter amplifier is designed so that a small change in voltage (V in) changes the small current through the base of the transistor whose current amplification combined with the properties of the circuit means that small swings in V in produce large changes in V out. [94]

  6. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

  7. Electrical resonance - Wikipedia

    en.wikipedia.org/wiki/Electrical_resonance

    A tesla coil is a high-Q resonant circuit. Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close ...

  8. Field-programmable gate array - Wikipedia

    en.wikipedia.org/wiki/Field-programmable_gate_array

    However, schematic entry can allow for easier visualization of a design and its component modules. Using an electronic design automation tool, a technology-mapped netlist is generated. The netlist can then be fit to the actual FPGA architecture using a process called place and route , usually performed by the FPGA company's proprietary place ...

    Result: 0 0 1 1 1 1 1 1 0 0 (14 steps, six "1"s total). This is one of several nonequivalent machines giving six 1s. Unlike the previous machines, this one is a busy beaver for Σ, but not for S. (S(3) = 21, and the machine obtains only five 1s. [14]) Animation of a 4-state, 2-symbol busy beaver
