摘要： Constant and accurate signal gain systems based on controlling oscillator loop gain. A constant gain positive feedback network and an amplifier form an oscillator. Only when the oscillator loop gain is at least one does the oscillator produces an AC signal. Negative feedback of the oscillator's AC signal level is used to keep the loop gain close to or at the value of one by controlling the loop gain of the oscillator circuit. By maintaining the loop gain of the oscillator circuit substantially constant the signal gain is also maintained substantially constant.

摘要： Constant and accurate signal gain systems based on controlling signal amplifier gain level by applying the signal amplifier output signal to a signal level divider with a set ratio. The output signal of the signal level divider is applied to one input of the gain control amplifier, which is a differential amplifier, while the signal amplifier input signal is applied to the other input. The gain control amplifier output level is used to control the gain level of the signal amplifier. The gain control amplifier output level forces by negative feedback the gain control amplifier input levels to be substantially equal thus maintaining the signal amplifier gain level substantially constant.
