A neural digital processor (10) that includes circuitry (14) for applying a function ANLF to neural potentials. ANLF approximates a non-linear activation function NLF. The circuitry includes another neural processor which operates with another non-linear activation function CNLF. CNLF is a simple function, for example a ramp. The circuitry (14) may comprise elements (361, 362, 64) in common with apparatus (75) for calculating a derivative of the approximation function ANLF. The precision of approximation of the non-linear activation function NLF can be predetermined.
