8. Analog phasemeter with scales
This classification includes phase meters using flip-flops or logic circuits.
With the help of electronic processes, waves are transformed into rectangular signals, phase detection is performed by flip-flops or logic circuits; phase shift indication is given by a pointer device after the integration of an analog sequence.
8.1 Bistable rocker phase meters
The voltages to be compared are processed by clipper amplifiers, which transform the alternations into square-wave signals that switch from low to high or vice versa at the exact moment when the voltages go to zero. The square-wave signals are transformed into short pulses of suitable direction, which can drive a bistable flip-flop, giving a larger signal at the output the greater the...
