中文摘要 | 對一位實際電路設計工程師而言,示波器的使用是不可或缺的儀器,現今示波器 的製造技術與功能已相當強並且穩定,然而在放大器、濾波器等實際電路設計時,常需要頻 率響應的測試,這時候只靠示波器對波形的量測是不夠的。本專題是製作頻率響應控制器, 將待測電路的頻率響應Bode Plot直接顯示出來,使做電路分析的工作者可以做實際電路的 頻率響應量測。一般運算放大器(Operational Amplifier)它的開迴路增益的單位增益頻寬 (Unit-gain Bandwidth)約數拾Hz到數百KHz,本專題製作以10Hz~100KHz頻寬做信號掃 瞄的範圍,作純量的增益頻率響應的顯示,可位移指標並顯示相對位置的頻率及增益數值。 |
英文摘要 | For a circuit programmer, the performance and function of the scope is quite good and steady, but during the actual practicing, only a scope is not enough. There're still some demand of frequency response testings. This project is to produce a controller which can expanse the analytic function to measure frequency domain, to show Bode Plot of the frequency domain on the LCM moniter, this project can't only show the wave form, but also the frequency analytic function, so that a circuit programmer can do his job better. The unit gain frequency bandwidth of a normal operational amplifier is ranged from several Hz to several hundred KHz. The the scan function contreller is focus on the rang of ten Hz to one hundred KHz, the outcome is to show the magnitude frequncy response and shift the cursor to display the relation of the position of the Bode Plot. |
