Such assumptions sometimes may result in narrow frequency band, large time delay and unstable system.
这样得到的控制系统频带较窄、时滞大,还有可能出现控制系统不稳定。
Based on T type filter, the new ballast can achieve a wide dimming range with a very narrow frequency variation range, and it can operate with low lamp current crest factor.
基于T型滤波器的调光方法,能在很窄的工作频率范围内实现深度调光,同时具有灯电流波峰因数低的优点。
The speech is sparse in time-frequency domain, so the energy of voice signal only concentrates on some narrow frequency, and the energy of voice sources are not overlap each other.
由于语音信号是时频稀疏的,语音信号的能量主要集中在某些窄带上,且各语音源的能量集中区域不交迭。
