Abstract: A gain adjustment circuit for maintaining the overall gain of a multi-component apparatus at a relatively constant level is disclosed. A multi-component apparatus in which the gain adjustment circuit may be implemented includes a first component and a second component. The first component has a variable gain, and receives as input a control signal which determines the gain of the component. The second component has an adjustable gain, and provides as output an output signal which affects the control signal fed to the first component. The gain adjustment circuit adjusts the adjustable gain of the second component based upon the control signal fed to the first component to maintain the overall gain of the components at a relatively constant level. More specifically, if the control signal is at a level which causes the variable gain of the first component to be high, then the gain adjustment circuit sets the adjustable gain of the second component to a low level.
