Abstract:
1. A method for controlling system output comprising the steps of providing an input signal, providing an adjustable system gain for varying the amplitude of the input signal, establishing a first kneepoint wherein the first kneepoint represents a first output value corresponding to a first value of the input signal, establishing a second kneepoint, wherein the second kneepoint represents a second output value corresponding to a second value of the input signal, establishing a companding ratio as a ratio of the absolute value of the difference of second input signal value less the first input signal value, divided by the absolute value of the difference of the second output signal value less the first input signal value, adjusting the system gain, adjusting the companding ratio in response to the adjusting of the system gain by adjusting one of the kneepoints relative to the other.
