Abstract:
Rectifying circuitry comprising:first and second input terminals for respectively receiving first and second input signals of varying amplitudes;a positive signal integrator and a negative signal integrator;circuit means responsive to the first and second input signals having an amplitude greater than a first predetermined value and also being responsive to the amplitude of the first input signal relative to the amplitude of the second input signal for applying the one of the first and second input signals which is positive relative to the other to the positive signal integrator and for applying the other one of the first and second input signals to the negative signal integrator; andsaid circuit means also being responsive to each one of the first and second input signals having an amplitude which is smaller than said first predetermined value for alternatively applying the first and second input signals to the positive and negative signal integrators, such that the first input signal is applied to the positive signal integrator and the second input signal is applied to the negative signal integrator during a first time period and the first input signal is applied to the negative signal integrator and the second input signal is applied to the positive signal integrator during a second time period; where the second time period is substantially equal to the first time period.
