提出了基于频域校准相位抵消法的低中频接收机方案,同时分析其性能以及i,Q两路的相位、幅度误差带来的影响。
The performance of the plan and the effects caused by phase and amplitude error in I and Q path were given.
两个传输天线都发送相同的数据,而放置的这个接收天线会接收来自这些传输天线的180度相位差的信号,从而信号相互抵消。
Both transmitting antennas send the same data, but the receiving antenna is placed so it receives signals from the transmitting antennas that are out of phase so they cancel out.
这些延迟会造成“梳状滤波效应”(相位的抵消和叠加),这会改变拾取信号的音质。
This delay can cause "comb filtering" (phase cancellation and addition), which alters the miked signal's tone.
正是有这一相位差,才使强迫力对振动系统所做的功正好抵消阻尼力对振动系统所做的负功,以保证稳定振动的等幅性。
This leads to the result that the work of force counteracts the work of damp force, and that the swing of steadily oscillation is the same.
这当然会抵消个别相位的效果。
It would certainly cancel out the effect of the individual aspects.
这当然会抵消个别相位的效果。
