Meanwhile it can filter the waveform and gather the envelope and calculation the current peak and max steepness of lightning by length of erased magnetic record. thirdly we need analyze the difference of length of erased magnetic record between kinds magnetic tape or pre - recorded sine wave on magnetic tape, and finding the min and max lightning current that can be recorded by magnetic tape. then we confirm the type of the magnetic tapes and the way of installing which fit to the line towers
同時對該波形進行濾波消噪，提取包絡線計算磁帶消磁長度和雷電流峰值及最大陡度第三部分根據mtlcd得出的數據分析不同雷電流通道下不同磁帶、不同預錄正弦波消磁長度的差異及磁帶可以記錄的最小雷電流和最大雷電流，找到可以在輸電鐵塔角鋼上安裝使用的磁帶及其放置方式。 -
The second part is to develop the program of mtlcd about the magnetic tape wave - form process using matlab software. the mtlcd can display the signal of waveform with the magnetic record being erased in the screen of computer. the observer also can drought or zoom in the waveform at will
第二部分利用matlab作為開發工具編寫磁帶波形處理軟體mtlcd ，該軟體可將磁帶被消磁后的波形信號顯現在電腦屏幕上，並能對波形隨意拉伸放大觀察每一個細節。
