This circuit breaks an input voltage signal down into its components: (1) the absolute value and (2) the polarity or ‘sign’ (+ or –). It will handle direct input voltages as well as alternating ...
The circuit in Figure 1 generatesan output voltage that you canmeasure to determine whether two sinewaves have a quadrature relationship. Ifthe output voltage is 0V, the inputs (Ï•1and Ï•2) are exactly ...
