Clever Use of Nyquist: How to Generate High-Frequency Signals Using DAC Characteristics?

In the field of digital signal processing, the Nyquist sampling theorem establishes the fundamental criterion for signal digitization— to accurately reconstruct a continuous signal, the sampling frequency must be at least twice the highest frequency of the signal.However, engineers have observed an interesting phenomenon: in practical applications, we often generate signals exceeding 500MHz using a … Read more
