1. A method of processing electrical signals which span a large dynamic range in order to enable the signal to be processed in its entirety without the need for the signal gain or signal attenuation to be dynamically altered by an amount determined by the signal level, comprises splitting of the signal along two or more paths each having a different amount of amplification or attenuation, the passing of each of these two or more different signals into one of two or more smaller dynamic range circuits which produce a logarithmically scaled representation of the average magnitude of the signal level at its input and the summation of the logarithmic outputs of the two or more smaller dynamic range circuits to produce a resultant logarithmically scaled signal representative of the average magnitude of the input signal over said large dynamic range.
