Table 3 Comparison of the 2nd order filters in the Volterra and the MMD structure for loudspeaker identification and linearization
"... In PAGE 18: ... In this case, longer adaption time is not a serious problem, because identification is done only once without any time constraints. Table3 summarizes the memory length and the required filter operations for the nonlinear filter part for both realizations. Even though the memory length of the MMD filter is twice as long, the number of filter operations in the identification phase is similar to that of the general Volterra case.... ..."
Table 1: Mean Squared Error Figures for Fully Coupled and Partially Decoupled Volterra Filters
Table 1 shows the computational complexity of a 5th-order Volterra inverse with different wavelet filter lengths. It can be seen that the complexity of the inverse increases dramatically with higher wavelet filter length. For system operating with high sam- pling rates, real time compensation using a Volterra inverse is thus limited to lower order, short memory cases. Therefore, we have to truncate the memory length of the Volterra inverse in order to reduce the complexity for real time implementation. In the next section, computer simulations will be presented to demonstrate the performance of the truncated Volterra inverse.

Identification of NLSs with memory Table2 shows the eigenvalue spread of the functional covariance matrix of several Volterra and Fourier models with Q=2, for orders N={5, 10} and for the same input distributions of Table 1.

Table 2. Values of AC BF and AC BH for truncated 3rd- and 5th-order Volterra kernels with Daubechies and Symlets filters of length 14
"... In PAGE 3: ... First, define the squared sum of the pth-order kernel coeffi- cients of wavelet filter length C6 as BV B4D4B5 C6 BP BEC6A0BE CG D1 BD BPA0B4BEC6A0BEB5 A1A1A1 BEC6A0BE CG D1 D4 BPA0B4BEC6A0BEB5 CYCW D4 CJD1 BD BN A1A1A1 BND1 D4 CLCY BE (17) and the squared sum of the truncated pth-order kernel coefficients of memory length C3 as BV B4D4B5 C3 BP B4C3A0BDB5BPBE CG D1 BD BPA0B4C3A0BDB5BPBE A1A1A1 B4C3A0BDB5BPBE CG D1 D4 BPA0B4C3A0BDB5BPBE CYCW D4 CJD1 BD BN A1A1A1 BND1 D4 CLCY BE (18) The ratio of the two squared sums, gives a measure of the approx- imation accuracy of the truncated pth-order kernel to the original kernel, denoted AC D4 AC D4 BP BV B4D4B5 C3 BV B4D4B5 C6 (19) where BC AK AC D4 AK BD. Table2 shows the values of AC BF and AC BH for the Daubechies and Symlets filters of length C6 BPBDBG. It can be seen from the tables that, for both truncated 3rd- and 5th-order Volterra kernels with memory length C3 BP BDBN BF and 5, the Symlets filter always results in a higher AC BF and AC BH ratios.... ..."
Table 1: Invariant simulation probabilities. For each individual simulation there were two more important parameters, which were varied between simulations as part of the study. The rst of these parame- ters was the carrying capacity of a location ( eld) with respect to the prey species. The Lotka-Volterra oscillations are produced without this factor, and cannot be stochastically modelled without an exponential explosion in the populations. How- ever when carrying capacity was introduced by Volterra [Volterra, 1931] the result- ing Volterra Oscillations do lend themselves to stochastic modelling. The carrying capacity was the maximum prey population that a location could support in the absence of predators. This was therefore a limiting factor to prevent prey popu- lations rising exponentially. The prey birth routine reduces the the probability of 5

Table1 lists all the prob- abilities relating to a single time-step; these remain invariant throughout all the simulations. These parameter values were those used by Wol in his work, and have been chosen since they produce the desired Predator-Prey oscillations for a... ..."

"... In PAGE 26: ... However, some timing failures that are embedded in short paths may not cause delay faults at normal operating conditions. Table3 -1 lists the causes of timing failures and the possible testing techniques for detecting them. Although all of these failures may be detected by delay fault testing, the success of detection depends on the significance of the excessive delay in the defective circuit.... In PAGE 27: ...
