Abstract : temporal properties of the second - ordre process with a chirped incident pulse are theoretically calculated . the chirp influences the irradiance and the pulse shape of the second harmonic wave with large phase mismatch . the phase distortion of all three waves is dependent more strongly on the chirp than on the phase mismatch 文摘:討論了在大相位失諧下,基波為頻率啁啾脈沖的二次諧波產生過程,結果表明選取合適的啁啾參量可以使二次諧波的光強提高,但同時會使其波形和相位發生變化.三波相位的畸變主要取決于入射的基波啁啾脈沖,而與相位匹配的失諧量關系不大

Iir filters are a kind of digital filters with recursive structure and are primarily used for high data throughput applications that can tolerance phase distortion and require a sharp cut - off characteristic 本文討論的iir濾波器是一種遞歸結構的數字濾波器,主要用于能夠容忍相位失真而要求具有良好的衰減特性的高數據處理量的系統中。

Based on fractional sampling method , a new super - exponential iteration decision feedback blind equalization algorithm for severely nonlinear phase distortion channels was proposed 因此針對嚴重頻率衰落和非線性相位失真信道,提出了一種分數采樣的混合盲均衡算法,并獲得了較快的收斂速度和較小的剩余均方誤差。

As the uwb characteristics are represented at not only directional diagram and impedance bandwidth but also phase distortion 由于超寬帶特性不僅僅體現在方向圖和阻抗的帶寬上,而且要考慮其相位失真。
