phase delay vs phase lag

Both 'phase delay' and 'phase lag' are correct terminologies used in the context of signal processing and electronics. They refer to the difference in phase between two signals. The choice between 'phase delay' and 'phase lag' may depend on the specific context or preference, but both are commonly used and understood.

This phrase is correct and commonly used in the context of signal processing and electronics to refer to the difference in phase between two signals.

"phase delay"

It is used to describe the time difference between two waveforms or signals in a system. 'Phase delay' indicates the amount by which one signal lags behind the other in terms of phase.

Examples:

The phase delay between the input and output signals should be minimized for optimal performance.
The system introduces a phase delay of 90 degrees.
The phase delay can be compensated using a phase shifter.
The phase delay causes distortion in the signal.
The phase delay is crucial for maintaining signal integrity.

Alternatives:

phase shift
phase difference
phase offset
phase discrepancy
phase distortion

This phrase is correct and commonly used in the context of signal processing and electronics to refer to the difference in phase between two signals.

"phase lag"

It is used to describe the time difference between two waveforms or signals in a system. 'Phase lag' indicates the amount by which one signal lags behind the other in terms of phase.

Examples:

The phase lag between the reference and output signals is significant.
The system exhibits a phase lag of 45 degrees.
The phase lag needs to be compensated for accurate signal processing.
The phase lag can be adjusted using a phase equalizer.
The phase lag affects the overall system performance.

In the lag phase, acclimation or adaptation of the degrading bacteria takes place with almost no removal of the test chemical; then the initial growth of these bacteria occurs.
Degradation phase The time from the end of the lag period to the time when 90 % of the maximum level of degradation has been reached.
In the lag phase, acclimation (or adaptation) of the competent bacteria takes place with almost no removal of the test chemical; then the initial growth of these bacteria occurs.
information on lag and plateau phases, test duration, the degree of elimination of the test chemical and that of the organic medium in the control unit, together with statistical information and statements of biodegradability and validity of the test;
the lag phase, degradation phase, 10-day window and slope should be clearly indicated (Annex I).
