摘要： A generally asymptotic incoming audio signal is split into positive and negative components. Two separate polarity-independent variable-gain amplifiers act upon the positive and negative components of the signal. A positive (negative) peak rectifier circuit monitors the positive (negative) output component of the signal. Each rectifier has a comparator amplifier that generates an error voltage. The error voltages assign gain factors to the positive (negative) variable gain amplifiers, thereby ensuring that the peak amplitudes of the positive (negative) are the same. A combining amplifier sums the positive (negative) components of the signal to form an amplitude symmetric signal. This signal may be used to modulate a radio frequency carrier to its maximum potential regardless of input signal waveform asymmetry.

摘要： Presented is a control circuit for controlling, i.e., preventing, filter overshoot in stereophonic broadcast equipment, particularly stereophonic FM broadcasting equipment. The circuitry includes an input clipper cooperating with a phase-lag network and a second clipper to condition the primary information signal to anticipate filter overshoot and counteract it through cooperation of comparator and summing circuits that add back into the amplitude-limited signal the clipped off components that exceed in amplitude the amplitude-limited signal, but which are added back in opposite phase.
