ABSTRACT:
A signal transient improvement device includes a delay circuit (1-13) receiving an input signal (C) and having an output supplying an output signal which is a version of the input signal either delayed by a predetermined amount (T3), or delayed by a controllable amount less than or equal to the predetermined amount, and a control circuit (15-23) for controlling the delay circuit. The control circuit calculates the second derivative of the input signal to obtain a control signal, the sign of which indicates whether the input signal is to be delayed by the predetermined amount, or delayed by a controllable amount less than or greater than the predetermined amount, while the amplitude of the control signal indicates the magnitude of the controllable amount less than or greater than the predetermined amount by which the input signal is to be delayed.
