| Abstract: |
| The differential transform of pulse waves described in this paper is a special method by which mathe matical transforms of certain functions between a coordinae system in v, t and the present coordinate system in v, dv/dt can be realized. The purpose of the transform is mainly to evaluate exactly the rate changes of irregular spikes with changes in potential. Differential transforms of several common functions are presented, as well as the differentiator designed for this purpose and the laboratory installation. A rate change pattern is shaped on the screen
of a dual-beam oscilloscope by means of the differentiator, which is very useful for researching muscle or nerve spikes in medical science. |
