Nyquist

例句：

1. 1.The Nyquist frequency is the lowest frequency at which a signal can be transmitted without distortion.
   奈奎斯特频率是信号在不产生失真的情况下可以传输的最低频率。
2. 2.In digital communication, the Nyquist limit determines the maximum data rate that can be achieved with a given bandwidth.
   在数字通信中，奈奎斯特极限决定了给定带宽下可以实现的最大数据传输速率。
3. 3. The Nyquist sampling theorem states that any discrete-time signal can be reconstructed from its samples if the sampling frequency is greater than twice the Nyquist frequency.
   奈奎斯特采样定理指出，如果采样频率大于奈奎斯特频率的两倍，那么任何离散时间信号都可以从其样本重建出来。
