Linear Feedback Shift Register Calculator — free online calculator.
Formula
- Linear Feedback Shift Register Calculator calculates its result from State (binary), Tap positions from right, comma-separated. It uses the formula One LFSR step: feedback bit = XOR of selected tap bits; shift and insert feedback.. Change any input to recalculate the result instantly.
- The main inputs are State, Tap positions from right, comma-separated. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Linear Feedback Shift Register
- State: 1011 binary
- Tap positions from right, comma-separated: 0,1
Using State (binary) = 1011, Tap positions from right, comma-separated = 0,1, the calculated result is 0110.
