Logic gate

•  Flip-flop (electronics)

  In digital circuits, a flip-flop is a term referring to an electronic circuit that has two stable states and thereby is capable of serving as one bit of memory. Today, the term flip-flop has come to mostly denote non-transparent (clocked or edge-triggered) devices, while the simpler transparent ones are often referred to as latches; however, as this distinction is quite new, the two words are sometimes used interchangeably (see history).

•  Majority function

  In Boolean logic, the majority function (also called the median operator) is a function from n inputs to one output. The value of the operation is false when n/2 or more arguments are false, and true otherwise. Alternatively, representing true values as 1 and false values as 0, we may use the formula The "−1/2" in the formula serves to break ties in favor of zeros when n is even; a similar formula can be used for a function that breaks ties in favor of ones.

•  Sheffer stroke

  In Boolean functions and propositional calculus, the Sheffer stroke, named after Henry M. Sheffer, written "|" or "↑", denotes a logical operation that is equivalent to the negation of the conjunction operation, expressed in ordinary language as "not both". It is also called the alternative denial, since it says in effect that at least one of its operands is false. In Boolean algebra and digital electronics it is known as the NAND operation ("not and").

•  Inverter (logic gate)

  In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. The truth table is shown on the right. This represents perfect switching behavior, which is the defining assumption in Digital electronics. In practice, actual devices have electrical characteristics that must be carefully considered when designing inverters. In fact, the non-ideal transition region behavior of a CMOS inverter makes it useful in analog electronics as a class A amplifier (e.g.

•  Fan-out

  Fan-out is a measure of the ability of a logic gate output, implemented electronically, to drive a number of inputs of other logic gates of the same type. In most designs, logic gates are connected together to form more complex circuits, and it is common for one logic gate output to be connected to several logic gate inputs. The technology used to implement logic gates usually allows gate inputs to be wired directly together with no additional interfacing circuitry required.

•  Toffoli gate

  In computer science, the Toffoli gate (also CCNOT gate), invented by Tommaso Toffoli, is a universal reversible logic gate, which means that any reversible circuit can be constructed from Toffoli gates. It is also known as the "controlled-controlled-not" gate, which describes its action.

•  Transmission gate

  A transmission gate is an electronic element. It is a good non-mechanical relay, built with CMOS technology. Sometimes known as an analog gate, analogue switch or electronic relay depending on its use. It is made by the parallel combination of an nMOS and a pMOS transistor with the input at the gate of one transistor being complementary to the input at the gate of the other.

•  Fredkin gate

  The Fredkin gate is a computational circuit suitable for reversible computing, invented by Ed Fredkin. It is universal, which means that any logical or arithmetic operation can be constructed entirely of Fredkin gates. The basic Fredkin gate is a controlled swap gate that maps three inputs (C, I1, I2) onto three outputs (C, O1, O2). The C input is mapped directly to the C output. If C = 0, no swap is performed; I1 maps to O1, and I2 maps to O2.

•  AND gate

  The AND gate is a digital logic gate that implements logical conjunction - it behaves according to the truth table to the right. A HIGH output (1) results only if both the inputs to the AND gate are HIGH (1). If neither or only one input to the AND gate is HIGH, a LOW output results. In another sense, the function of AND effectively finds the minimum between two binary digits, just as the OR function finds the maximum.

•  OR gate

  The OR gate is a digital logic gate that implements logical disjunction - it behaves according to the truth table to the right. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is HIGH, a LOW output (0) results. In another sense, the function of OR effectively finds the maximum between two binary digits, just as the complementary AND function finds the minimum.

•  Wawatam Township, Michigan

  Wawatam Township is a civil township of Emmet County in the U.S. state of Michigan. As of the 2000 census, the township population was 705. The village of Mackinaw City is located mostly within the township. The township is named after Wawatam, an Ojibwa Chief noted for rescuing British trader Alexander Henry from the Ojibwas' capture of Fort Michilimackinac in 1763.
