然而，DYNAS DSP的不对称滤波器响应往往意味着的T - 4970将很难锁定到一个以上的DX信号或信号之间的地方(第)。

However, the DYNAS DSP asymmetrical filter response often means the T-4970 will have difficulty locking on to a DX signal above or in between the local signal (s).

另外，三相四线制有源电力滤波器能有效地抑制零线电流，并能有效地解决系统的不对称问题。

Moreover, three-phase four-wire active filters can suppress zero line current, and solve symmetric problem of system effectively.
