虽然电路对温度响应性很低，调制的高频率信号也会由于热行为产生的复杂的互相调制现象而发生失真。
A modulated high-frequency signal is distorted by the thermal behaviour through complex intermodulation phenomena, although the temperature response of the circuit is slow.
现有的随机共振系统只能应用于低频率信号检测或待测信号频率已知的高频率信号检测，这束缚了系统的实用范围。
Stochastic resonance can only be applied to low-frequency signal or the known high-frequency signal detection. So the applications of the system are severely constrained.
对于特定的信号类型，例如低电平或高频率，则不宜使用模拟背板，以避免造成信号劣化。
For certain signal types, such as low level or high frequency, the analog backplane should not be used to avoid possible signal degradation.
进行电路设计，使DMM能测量出较高频率函数信号的有效值和频率。
By circuit design DMM can measure function signal's RMS and frequency.
此外，较高频率的声音是很少用于地震成像方面的，因为该高频声音的能量会消耗在土里，导致其返至地面的信号对于成像基本没有作用了。
The higher-frequency sounds are of little use for seismic imaging because they dissipate in the earth, contributing little to images based on the signals that echo up to the surface.
数字式输电线使用一个网络，以一个高频率被适应的力量网络(HFCPN)著名，传送数据和电信号。
Digital Power line USES a network, known as a High Frequency Conditioned Power network (HFCPN), to transmit data and electrical signals.
结论采用复杂可编程逻辑器件替代通用数字集成器件，可提高系统的高频率特性，并提高信号源的信噪比。
So, complex programmable logic device can improve the system's high-frequency performance and signal to noise ratio.
根据Nyquist定理，采样率必须是被测信号最高频率分量的两倍以上。
According to the Nyquist Theorem, the sampling rate must be more than twice the maximum frequency component of the signal being measured.
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。
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.
