1. Plural of aliasing; instances or effects of aliasing, particularly in signal processing or computer graphics where high-frequency components are misrepresented as lower frequencies due to insufficient sampling.
Usage: technical; computing; signal processing

Examples

• The engineer worked to reduce aliasings in the digital audio signal.
• Aliasings can occur when sampling rates are too low for the input frequency.
• The graphics software applies anti-aliasing filters to minimize aliasings on diagonal lines.
• In image processing, aliasings appear as jagged edges or moiré patterns.
• The team investigated various aliasings that appeared in their radar data.
