A general disadvantage of ring counters is that they are lower density codes than normal binary encodings of state numbers. A binary counter can represent 2 N states, where N is the number of bits in the code, whereas a straight ring counter can represent only N states and a Johnson counter can represent only 2N states. This may be an important ...
Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [ 1]
STGs were first proposed in 1981, under the name Signal Graphs, by Leonid Rosenblum (in Russian) in. [2] They were studied more formally and applied to the design of asynchronous interfaces by Alex Yakovlev in 1982, in his PhD thesis [3] (in Russian). They were later presented in English in 1985, in two independent sources, one by Rosenblum and ...
Asynchronous circuit ( clockless or self-timed circuit) [1] : Lecture 12 [note 1] [2] : 157–186 is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components. [1] [3] : 3–5 Instead, the components are driven by a handshaking circuit which indicates a completion of a set of ...
In computing, a linear-feedback shift register ( LFSR) is a shift register whose input bit is a linear function of its previous state. The most commonly used linear function of single bits is exclusive-or (XOR). Thus, an LFSR is most often a shift register whose input bit is driven by the XOR of some bits of the overall shift register value.

In electronics, metastability is the ability of a digital electronic system to persist for an unbounded time in an unstable equilibrium or metastable state. [1] In digital logic circuits, a digital signal is required to be within certain voltage or current limits to represent a '0' or '1' logic level for correct circuit operation; if the signal ...
