The Nyquist Rate is the minimum sampling rate required to accurately capture and reconstruct a continuous-time signal without losing any information, which is at least twice the highest frequency present in the signal. This concept is crucial for transitioning between continuous-time and discrete-time signals, ensuring that signals are sampled properly to avoid distortion or aliasing. Understanding the Nyquist Rate also plays a vital role in quantization and coding processes, as it informs how often a signal should be sampled to maintain its integrity.
congrats on reading the definition of Nyquist Rate. now let's actually learn it.
