Nyquist Frequency, also known as the folding frequency, is a term used in digital signal processing and communication systems. It refers to the highest possible frequency that can be accurately sampled or transmitted without causing aliasing. Synonyms for Nyquist Frequency include Nyquist Rate, Nyquist Limit, Shannon-Nyquist Frequency, and Sampling Frequency. Additionally, in certain contexts, the term Aliasing Frequency and Nyquist-Shannon Sampling Theorem Frequency are used interchangeably. The concept of Nyquist Frequency plays a crucial role in digital audio, image processing, and various other signal processing applications. Understanding the implications of Nyquist Frequency is thus essential for proper signal processing and accurate data transmission.
