An adaptive filter for spectral line enhancing comprises a delay line for delaying an input signal Xj by a fixed time delay. A transversal filter, whose input is connected to the output of the delay line, filters the delayed signal, the output of the filter comprising a signal Yj. A summer, having its inputs to signals Xj and Yj subtracts the signal Yj from Xj, the output of the summing means being the error signal epsilonj. A multiplier having a gain of mu multiplies the input signal epsilonj by a gain of mu, the output of the multiplier being fed back to the filter, to cause the weights to be readjusted.
