您要查找的是不是:
- Nyquist frequency acts as a mirror, folding over any frequency above it. 奈奎斯特频率相当于一面镜子,将任何高于它的频率进行折叠。
- Nyquist frequency is the name of the highest frequency that can theoretically be represented in a digital audio system. 奈奎斯特频率即理论上可以通过数字音频系统呈现的最高频率。
- This is equivalent to requiring that the Nyquist frequency be strictly greater than the bandwidth or the signal. 一个频率正好是采样频率一半的正弦信号,通常会混叠成另一相同频率的正弦信号,但它的相位和幅度改变了。
- Nyquist frequency defined as the highest spatial frequency where the sensor can still faithfully record image detail. Beyond the Nyquist frequency aliasing occurs. 奈奎斯特频率的定义是:感光器能够忠实纪录影像细节的最高空间频率。在此频率以上就会发生混肴现象。
- The results show that alignment between pixels of image bundle and input pattern has cyclic variation on measuring result of the CTF. The CTF value decreases with increasing of the frequency under Nyquist frequency. 结果表明,线列光纤传像束对比度调制传递函数值随位相呈周期性变化,在输入的空间频率小于Nyquist频率时,对比度调制传递函数值随频率的增大而减小。
- In such a case, there would be an infinite number of possible and differen' sinusoids (of varying amplitude and phase) of the Nyquist frequency component that are represented by the discrete samples. 引入低通滤波器或提高低通滤波器的参数;
- To adequately preserve the shape of your signal, you should sample at a much higher rate than the Nyquist frequency, generally at least 5 or 10 times the maximum frequency component of your signal. 为充分保证信号的波形不失真,你的采样频率应比Nyquist频率高出许多,通常是你信号最高频率的5到10倍。
- Nyquist frequency and aliasing distortion 奈奎斯特频率和折叠失真
- Modulation Transfer Function of CCD Camera at Nyquist Frequency CCD相机在系统奈奎斯特频率处的调制传递函数
- He varied the transmission frequency. 他变换了无线电传送的频率。
- Innovative switching output stage permits usable outputs beyond Nyquist frequency 创新的开关输出级允许使用超过奈奎斯特频率的输出信号
- A unit of frequency equal to one cycle per second. 赫兹频率的单位,等于每秒一周
- Innovative switching output stage permits useable outputs beyond Nyquist frequency 创新的开关输出级,允许使用超过奈奎斯特频率的输出频率
- An HPF can be made from a BPF by setting its centre frequency to be equal to the Nyquist frequency; 将通带滤波器中心频率设置到与奈奎斯特频率(即系统产生的最高频率值)相同的位置时,就可以用作高频滤波器;
- Both sets of names are supported in Nyquist. Nyquist对于这两组名称都支持。
- Fatal accidents have decreased in frequency over recent years. 近年来死亡事故发生的频率已经下降。
- We can often correlate age with frequency of illness. 年龄的大小往往与发病率有关。
- Accidents on that highway are happening with increasing frequency. 那条高速公路上车祸发生得越来越频繁。
- Write new effects with the built-in Nyquist programming language. 使用内建的Nyquist编程语言编写新的特效。
- He tuned his radio to the police frequency. 他把无线电调到警方的频率。
