Function generator. A simple analog function generator, circa 1990. A DDS function generator. Sine, square, triangle, and sawtooth waveforms. In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies.
50+1 rule is an informal term used to refer to a clause in the regulations of the Deutsche Fußball-Liga (German Football League). The clause states that, in order to obtain a license to compete in the Bundesliga and 2. Bundesliga, a club must either wholly- or majority-own its association football team. In case of majority ownership, the ...
However, generally they are considerably slower (typically by a factor 2–10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.
Rolling code. A rolling code (or sometimes called a hopping code) is used in keyless entry systems to prevent a simple form of replay attack, where an eavesdropper records the transmission and replays it at a later time to cause the receiver to 'unlock'. Such systems are typical in garage door openers and keyless car entry systems.
The raised-cosine filter is an implementation of a low-pass Nyquist filter, i.e., one that has the property of vestigial symmetry. This means that its spectrum exhibits odd symmetry about , where is the symbol-period of the communications system. Its frequency-domain description is a piecewise -defined function, given by:
A generator matrix for a linear [,,]-code has format , where n is the length of a codeword, k is the number of information bits (the dimension of C as a vector subspace), d is the minimum distance of the code, and q is size of the finite field, that is, the number of symbols in the alphabet (thus, q = 2 indicates a binary code, etc.).
