Nyquist limit 奈奎斯特频限 Maximum rate of transmitting pulse signals through a system. If B is the effective bandwidth in hertz (Hz), then 2B is the maximum number of code elements (bands) per sec which can be received with certainty, 12B is known as the Nyquist interval. 系统中传输脉冲信号的最大速率。如果B是系统的有效带宽(以Hz为单位),那么2B就是每 秒内能确切接收到的最大码元数(bands), 即奈奎斯特速率,而12B即被称为奈奎斯特间隔。 |
