信号的频域是什么意思?和时域有什么区别? - 知乎 The third axis is frequency which allows us to visually separate the sine waves which add to give us our complex waveform If we view this three-dimensional graph along the frequency axis we get the view in Figure 2 6b This is the time do main view of the sine waves Adding them together at each instant of time gives the original wave form
西门子博途扩展函数库LGF系列教程 (1)-LGF_Frequency 2、LGF_Frequency的使用 LGF_Frequency函数可以输出指定频率和占空比的脉冲信号。 在LGF的7信号发生函数 (7 Signal generators)中可以找到LGF_Frequency,将其拖拽到FB中,系统会提示创建背景数据块,这里我选择单独背景数据块,初始添加的代码如下图所示:
十分钟读懂旋转编码(RoPE) 旋转位置编码(Rotary Position Embedding,RoPE)是论文 Roformer: Enhanced Transformer With Rotray Position Embedding 提出的一种能够将相对位置信息依赖集成到 self-attention 中并提升 transformer 架构性能的位置编码方式。而目前很火的 LLaMA、GLM 模型也是采用该位置编码方式。 和相对位置编码相比,RoPE 具有更好的 外推性
