N-state with n equal or greater than 2 modified Linear Feedback Shift Registers (mLFSRs) having a non-reversible n-state switching function have been disclosed. An mLFSR can also contain a device that implements an n-state logic function of which one input is provided with a signal external to the mLFSR. The mLFSR can be in Fibonacci or in Galois configurations. N-state scramblers and corresponding descramblers applying an mLFSR are provided. N-state coding boxes apply non-reversible switching functions connected to n-state scrambling or descrambling functions. Sequence generators and detectors are also disclosed.
