A non-stationary signal is one whose frequency changes over time; e.g. human speech where frequencies vary over time depending on what words or syllables you are pronouncing. On the contrary, you have stationary signals where frequencies don't change over time; e.g. the signal: cos(20*pi*t)+cos(50*pi*t)+cos(200*pi*t) where all of the frequency components (20*pi, 50*pi, 200*pi) exist at all times.

IS EEG signal a stationary or non-stationary signal?
By nature, EEG signals are considered non-stationary due to their time-varying characteristics caused by factors like brain state changes and electrical artifacts. This non-stationarity makes it challenging to analyze EEG data using traditional stationary signal processing techniques and often requires specialized methods such as time-frequency analysis.
What is the definition of a non-moving charge?
A non-moving charge refers to an electric charge that is stationary or not in motion.
What does stationary mean in?
In any field, stationary means unmoving and won't be moving.
How does a Doppler radar differentiates a stationary target from a moving target using Doppler effect?
A Doppler radar differentiates a stationary target from a moving target by measuring the change in frequency of the reflected signal. For a stationary target, there is no change in frequency, while for a moving target, there is a shift in frequency due to the Doppler effect. By analyzing this frequency shift, the radar can determine whether the target is moving or stationary.
Can stationary have non zero angular acceleration?
No, an object is considered stationary when it has zero velocity and zero acceleration. Angular acceleration refers to the rate at which an object's angular velocity changes over time. If something has a non-zero angular acceleration, it means that it is rotating at a changing rate.

What does the C in CWT stand for?
The "C" in CWT stands for "Continuous." CWT, or Continuous Wavelet Transform, is a mathematical technique used in signal processing and analysis that allows for the decomposition of a signal into wavelets, enabling the analysis of varying frequency components over time. This method is particularly useful for analyzing non-stationary signals.

A non-moving charge refers to an electric charge that is stationary or not in motion.
What is the comment about the polarity of the stationary phase and mobile phase?
The polarity of the stationary phase and mobile phase in chromatography significantly influences the separation of compounds. Generally, if the stationary phase is polar, it will retain polar compounds more strongly, while non-polar compounds will move faster with the mobile phase. Conversely, a non-polar stationary phase will favor the separation of non-polar compounds. Understanding this polarity interaction is crucial for optimizing separation processes.
What does stationary mean in?
In any field, stationary means unmoving and won't be moving.
