ABSTRACT:
A non-linear emphasis circuit comprising a high-pass filter receiving an input signal, a compressor processing the output of the filter with such a variable gain as to decrease or increase responsive to an increase or a decrease of the output of the filter and an adder for adding the input signal and the output of the compressor at a predetermined rate for producing a non-linearly emphasized signal. The circuit has a structure adapted for production in an IC form and easy to design.
