Phase-Sensitive Sinusoidal Signals Detector
![](https://freecircuitdiagram.com/wp-content/uploads/2011/02/Phase-sensitive-detector-for-sinusoidal-signals.jpg)
Using the phase sensitive detector circuit below the magnitude of sinusoidal signal can be measured. Beside that, this circuit also can be used to measures 180°-out-of-phase inputs with proper polarity. But, it depends on the relationship to the reference with less than 1% error. This circuit uses a AD741J op amp. Here is the schematic diagram of the circuit and […]
