Device for transforming a signal by stabilization and increasing the dynamic of said signal

Abstract

Abstract Device for transforming a signal by stabilising and increasing the dynamic, comprising a source, a receiver for the waves, and an end-use system. Between the receiver and the end-use system it comprises a stabiliser and dynamic-enhancing assembly consisting of: - means of measuring values characteristic of the function f representing said signal; - means of determining for this function the unique ratios of similitude K0, K1, K2, K3 such that an external composition law denoted DELTA , which with each real K associates the function K DELTA f, defined by the expression: <IMAGE> (M: theoretical maximum of f), has the best dynamic range; - means of calculating the functions K0 DELTA f, K1 DELTA f, K2 DELTA f and K3 DELTA f; - means of transmitting the values thus determined to the end-use system. <IMAGE>
