forPeriodAndBank

public static MetaShift.GaloisData forPeriodAndBank(long period,
                                                    int bank)

forPeriodAndBankModulo

public static MetaShift.GaloisData forPeriodAndBankModulo(long period,
                                                          int bankModulo)

Look up the valid Galois LFSR feedback register values for the required resamplePeriod.

Parameters:

period - The minimum cycle resamplePeriod required

bankModulo - A deterministic selector which will always select the same pseudo random bank

Returns:

A valid Galois LFSR feedback register
