why is Y(t)=X(2t) time varient ??
Time-variant systems are those that change over time, meaning that their output depends on the current input as well as previous inputs. On the other hand, time-invariant systems have outputs that do not change over time and are only dependent on the current input.
Examples of time-variant systems include weather patterns, stock market trends, and biological processes. Time-invariant systems include simple mathematical equations, such as y = mx + b, and physical laws, like Newton's laws of motion.
We can determine if a system is time-variant by observing its output over time. If the output changes for the same input at different times, then the system is time-variant. If the output remains the same regardless of the time the input is applied, then the system is time-invariant.
The advantage of time-variant systems is that they can adapt and respond to changes in the environment. However, this also means that they can be unpredictable and difficult to control. Time-invariant systems, on the other hand, are more stable and predictable, but they may not be able to adapt to changing conditions.
Understanding the properties of time-variant and time-invariant systems is crucial in scientific research and experimentation. It allows scientists to design experiments and make predictions based on whether the system they are studying is time-variant or time-invariant. This knowledge also helps in choosing the appropriate mathematical models and tools for analyzing and interpreting data.
