例句与用法
- The modulation bandwidth and the relaxation oscillation frequencies of the laser are quite different at different injection powers and wavelengths
发现在不同的注入光强度和波长下，激光器的调制带宽和弛豫振荡峰频率会发生变化。 - Only when the length of ring cavity is below that value , relaxation oscillation happens , and frsl have good modulation response and large modulation bandwidth
只有当环形腔长度小于该临界值时，激光器才发生弛豫振荡，并具有理想的调制响应和大的调制带宽。 - And the waveform of the transmitted signals was designed based on the target distance ( 5 ~ 50m ) . the waveform is triangular fmcw with central frequency at 6ghz , modulation bandwidth 100mhz , modulation period 10 s , step frequency 0 . 2mhz , and step time 10ns
在此基础上,设计发射信号波形参数为三角形调频连续波,中心频率6ghz ,调制带宽100mhz ,调制周期10 s ,步进频率0 . 2mhz ,步进时间10ns 。 - On the basis of rate equations of frsl , power characteristics and extinction ratio of the converted light are discussed . the relation between relaxation oscillation , small - signal modulation response , modulation bandwidth and the length of fiber ring cavity is analyzed also
根据frsl满足的单模速率方程，讨论了采用frsl进行波长转换时转换光的功率特性和消光比，以及frsl的弛豫振荡特性、小信号调制响应、调制带宽与光纤环形腔长度的关系。 - It has been shown by our calculations that conductor loss is greatly reduced under velocity matching with relatively thick coplanar waveguide electrodes and thick buffer layer , but the characteristic impedance can not match with that of the external circuit at the same time , and the modulation bandwidth is confined in this case
然后，用一般的椭圆积分计算了普通共面波导型调制器的有效折射率、特征阻抗和导体损耗系数。通过计算发现，采用厚电极和厚缓冲层结构，在实现速度匹配的情况下，可以大大减小导体损耗，但是由于阻抗不能同时满足匹配，调制带宽受到限制。
