It is well known that the spectral Tau method based on the classical Jacobi polynomials (Jacobi Tau method) allows the approximation of infinitely smooth solutions of operator equations such that the truncation error approaches zero faster than any negative power of the number of basis functions used in the approximation as that number tends to [infinity].
Following Fatunla [12] and Lambert [22] we define the local truncation error associated with (3) to be the linear difference operator
We deduce a sampling series in terms of these functions for Hankel-band-limited signals and derive bounds for the truncation error of the sampling series.
But, just as with S-parameter simulation, repeated use of the convolution integral leads to errors in results caused by local truncation error.
The larger the truncation error is, the smaller the number of cutsets will be produced.
1960), the truncation error of the remote zone can be reduced by introducing a modification of Stokes' formula.
There are two sources of error in this equation, truncation error and roundoff error.
Interestingly, though the predictions obtained using the low frequency spectrum were good at low frequencies they showed a large truncation error at higher frequencies.
Specifically, as Broadridge publicly disclosed earlier today, when Broadridge reported voting results for "withholds", a truncation error occurred in reporting share numbers that exceeded eight digits.
