      Generator Matrix We shall now look at two ways of describing a linear code C. The first is given by a generator matrix G which has as its rows a set of basis vectors of the linear subspace C. If C is an [n,k]-code, then G will be a k × n matrix. The code C is the set of all linear combinations of the rows of G,

      The typical structure of a random number generator is as follows. There is a finite set S of states, and a function f : S → S. There is an output space U, and an output function g : S → U. We will always take the output space to be (0,1). The generator is given an initial value S0 for the state, called the seed. The seed is typically ...

      Definition. The generator of a diffusion process of the form (1) is the linear operator L, defined in (4). The generator is exactly analogous to the infinitesimal generator of a continuous-time Markov chain. Recall that for a time-homogeneous, continuous-time Markov chain, we defined the generator to be the matrix Q

      A generator is known as “synchronous” when the waveform of the generated voltage is syn-chronized with the rotation of the generator. Permanent magnets are used to provide the field excitation in a linear synchronous generator. Due to mechani-cal constraints, linear motors have large and variable airgaps [3]. Therefore, the

      The DS345 can frequency sweep any of its function outputs (except noise). You can sweep up or down in frequency using linear or log sweeps. Unlike conventional function generators, there are no annoying discontinuities or band-switching artifacts when sweeping through certain frequencies. The DS345’s DDS architecture inherently allows it to

Generated voltage of a DC machine is a linear function of the flux per pole, so it is also nonlinear with respect to the field current. n1 < n2 < n3 So if we have two voltages at two different speeds, with the flux per pole held constant: If we know generated voltage at one speed we can

      The function generator can perform linear and loga-rithmic frequency sweeps. (A linear sweep passes ”equal numbers of Hz per se-cond”, a logarithmic one ”equal numbers of octaves per second”). A sweep is definedby four parameters: type (Lin/ Log), start frequency, stop frequency, and sweep time. To set up these parameters in the order ...
