A systematic error can be avoided by ensuring proper calibration of measurement instruments, using standardized procedures and protocols, and conducting regular quality control checks. Additionally, employing multiple methods or cross-verification techniques can help identify and correct biases. Training personnel to understand and minimize potential sources of systematic error is also crucial for maintaining accuracy in measurements.
To help the user avoid this problem, the scale is sometimes printed above a narrow strip of mirror, and the user positions his eye so that the pointer obscures its own reflection. This guarantees that the user's line of sight is perpendicular to the mirror and therefore to the scale. Parallax is thus avoided.
Error has different meanings in different contexts. In some cases it is a synonym for "mistake". In this sense "Human Error" would be careless accidents that could be avoided with care. In Scientific terms, however, "error" simply refers to the difference between an observed value and it's theoretical "expected" value, regardless of whether this difference relates to a "mistake" by the experimenter, or is the result of some uncontrolled variable in the experiment.
In physics, the meaning of aliasing is the misidentification of a signal frequency, introducing error. In computing, aliasing means the saw-toothed or jagged appearance of diagonal or curved lines on a low-resolution mirror in computer graphics.

From the Vibration Analysis Dictionary (www.vibronurse.com): Aliasing - A phenomenon which can occur whenever a signal is not sampled at greater than twice the maximum frequency component, causing high frequency signals to appear at low frequencies. Aliasing is avoided by filtering out signals greater than half the sample rate. Anti-aliasing filter - A low-pass filter designed to filter out frequencies higher than 1/2 the sample rate in order to prevent aliasing.

Because no one is infallible.
Somthing in an experiment that could be avoided with care
A systematic error is a reproducible inaccuracy with a nonzero mean. It can be avoided by ensuring that the measuring equipment is not flawed.

To overcome the aliasing effect, you can increase the sampling rate or use an anti-aliasing filter before sampling the signal. Additionally, you can employ oversampling techniques or apply signal processing algorithms like interpolation or filtering to reduce or eliminate aliasing artifacts in the signal.
