Abstract
Method and apparatus are provided for processing a wide dynamic range analog signal which comprises a compressive nonlinear transfer function responsive to the average amplitude of the signal without feedback along the signal path. The invention employs frequency selective filtering and expansion of the compressed signal. The invention is applicable to any analog signal system having a plurality of channels carrying related signal information.
