2
As a key technology in digital quadrature demodulation system, the direct IF sampling filter with sharp cutting-off transition band can improve the performance of demodulation system.
中频采样是数字正交鉴相系统中的一项关键技术，具有锐截止特性的中频采样滤波器可以改善鉴相系统的性能。
3
If sampling length doesn't adapt rotative velocity, the results of calculation by FFT or periodogram analysis will lead to pseudo-periods, which distorts the principal value function terms.
若采样长度与回转速度不吻合，将会出现伪周期，使主值函数项中提取周期成分后的信号失实。
