In order to analyze speech, we needed to look at the frequency content of the detected word.
为了分析讲话，我们需要看看的检测词频的内容。
You will see that the five signal types closely parallel the five basic types of signal information: state, rate, level, shape, and frequency content.
这五类信号与状态、速率、电平、波形和频率五种基本信号一一匹配。
However, the information extracted from a frequency domain signal is based on the signal frequency content, as opposed to the shape or time-varying characteristics of the waveform.
然而，从频域信号中提取出的信息是以信号频率成分而非信号形状为基础。

The recommendations cover four areas: timing of a post, type of post (video, text, photo), frequency of posts and content of a post.
