Figure (a) is the polarity monitor with two LEDs, this device can differentiate the polarity of input signal or compare the size of the signal. You can use the potentiometer RP to adjust the sensitivity of the LEDs. Figure (b) can be used to add the signals of UE1, UE2, UE3. Figure (c) is the precision integrator circuit, the RC network must match the input signal. Figure (d) is the comparator circuit.
