PULSE-CODE MODULATION (PCM) In PCM, several pulses are used as a code group to describe the quantized amplitude of a single sample. For example, a code group of n on-off pulses (binary code) can represent 2n discrete amplitudes or levels, including zero level. In general, in an s-ary...
means for connecting said measuring device in predetermined intervals to said storage device to determine the numerical values of the charges thereof, a control device co-operating with said measuring device for causing transmission of a code signal when the determined numerical value is not divisible...
Before using numerical simulations, let us consider the steady-state solution of Eq. (12.3.2) when a CW beam is injected into the cavity. Setting both time-derivative terms to zero in this equation, the intracavity power Y=|U|2 satisfies the relation (12.3.4)[(Y−Δ)2+1]Y=|S|2....

A novel method for numerical modelling of noncollinear and nonlinear interaction of femtosecond laser pulses is presented. The method relies on a separate treatment of each of the interacting pulses by it’s own rotated unidirectional pulse propagation equation (UPPE). We show that our method enabl...
a simple fixed shift will not suffice in the case of adaptive delta modulation signals. This occurs because of the lack of a fixed numerical significance for bit positions in given data sequences. That is, a first operand may have a particular significance associated with a particular digit po...
Numerical simulation shows that this scheme can effectively resynchronize input signals with arbitrary delays to the local clock, and reduce input jitter. The scheme can also be applied to TDM 10 Gb/s and 40 Gb/s signals to over 100 Gb/s. 展开 ...
