Definition of PSQ
Phase Shift Quadrature (PSQ) is a technique used in signal processing and telecommunications to measure the phase shift between two signals that are 90 degrees out of phase, known as quadrature. PSQ is commonly expressed in degrees, providing a quantitative measure of the phase difference between the two signals.
Measurement of PSQ in Degrees
PSQ in degrees can be measured using various methods, including:
- Phase-Locked Loop (PLL):A PLL tracks the phase of an input signal and generates an output signal that is phase-locked to the input. The phase difference between the input and output signals can be measured and converted to degrees.
- Quadrature Detectors:Quadrature detectors are devices that multiply two signals that are 90 degrees out of phase. The output of a quadrature detector is a DC voltage that is proportional to the phase difference between the input signals.
PSQ measurements in degrees are commonly used in applications such as:
- Measuring the phase noise of oscillators
- Testing the performance of filters and other signal processing components
- Synchronizing digital communication systems
