A primitive polynomial satisfies some additional mathematical conditions and determines for the LFSR to have its maximum possible period, meaning (2n-1), where. As a result of this, a maximal period LFSR can visit all states, except the all-zero state, if not started from all-zero state. The LFSR is maximal-length if and only if the corresponding feedback polynomial is primitive over the Galois field GF (2). The copy-paste of the page 'Linear Feedback Shift Register' or any of its results, is allowed (even for commercial purposes) as long as you cite dCode!Įxporting results as a. An LFSR with an all-zero state will always produce the all-zero sequence. A Fibonacci 31 bit linear feedback shift register with taps at positions 28 and 31, giving it a maximum cycle and period at this speed of nearly 6.7 years.
