Abstract
In a signal processing chain producing an analog output signal from a digital input signal, dynamic range control applies to the analog output signal a dynamic range control gain as a function of an input gain applied to the digital input signal. The dynamic range control gain is applied to the analog output signal with a delay relative to the input gain applied to the digital input signal. A first flag signal is generated for the analog output signal and a second flag signal for the digital input signal, each flag assuming first and second levels and set to the first level when the signal from which the flag is generated is within a certain amplitude range. The first and second flag signals are compared and delay of application of the dynamic range control gain to the analog output signal controlled as a function of a result of the comparison.
