A formal representation of nerve spike trains in the form of a sum of rectangular functions is proposed. This formal instantaneous frequency function can be Fourier analyzed. The resulting algorithm has the useful properties of spike by spike calculations and an insensitivity to the mean (carrier) spike rate. The technique is also useful for producing a smooth (filtered) reconstruction of a spike train.
提出了一种以矩形函数之和的形式对神经脉冲序列进行形式化表示的方法。这种形式化的瞬时频率函数可以进行傅里叶分析。所得算法具有逐脉冲计算的有用特性，并且对平均（载波）脉冲率不敏感。该技术对于生成脉冲序列的平滑（滤波）重建也很有用。
