As the number of channels grew, they began facing agility problems.

随着渠道的成长，他们开始面临着敏捷度的问题。

Firstly, channel combination with fixed number of channels is optimized.

首先选择不同通道数时比较理想的通道组合。

This allows you to compare timing of a number of channels to a common signal.

这可以让你用一个公共信号来比较若干通道的时标。

Additionally, it is more flexible in choosing the filter length and the number of channels.

而且该方法对于滤波器长度和通道数的选取更具灵活性。

These switches can affect the performance if an application registers a huge number of channels.

如果应用程序注册大量通道，这些切换会影响性能。
