Abstract： High frequency electronic circuit experiment is commonly an experiment-based course in studying telecommunication. However， the negative feedback from undergraduate students is generally present in the experiments， including difficult understanding， complex operation， as well as error-prone when the students run such the experiments. With this in mind， we introduce Proteus simulation to the lecture to achieve a novel teaching philosophy through the combination of software and hardware， and thus the target course can be simulated before doing experiments. The Proteus simulation analysis of amplifying circuit with high frequency and little signal was implemented and used to observed in real-time the waveform of output signal， amplitude-frequency response characteristics， resonant frequency and transmission bands. The results indicate that the simulations were agreement well with the circuit experiments. It is suggested that Proteus simulation use is an efficient way to solve the problems existed in traditional teaching. Additionally， the students could have a good opportunity to master the modern simulation tool software so that perform likely advanced design ideas with relatively high ability. It clearly to see that the teaching approach proposed in this study achieved eventually the goals for both cultivating students and improving teaching quality.

引言

實(shí)驗(yàn)教學(xué)既是知識(shí)傳授的手段，也是將理論知識(shí)升到指導(dǎo)實(shí)踐的過程，更是基本工程素質(zhì)、實(shí)踐能力和創(chuàng)新能力培養(yǎng)的有效途徑。高頻電子線路作為通信、電子信息相關(guān)專業(yè)核心基礎(chǔ)課程，理論性強(qiáng)、知識(shí)點(diǎn)多，對(duì)學(xué)生實(shí)踐能力要求高[1]。高頻電路實(shí)驗(yàn)作為一門與理論課相配套的專業(yè)實(shí)踐課程，課程內(nèi)容安排及課程組織實(shí)施靈活性強(qiáng)，課程效果好，則有助于學(xué)生夯實(shí)理論知識(shí)、提高動(dòng)手實(shí)踐能力和創(chuàng)新能力，為后續(xù)課程設(shè)計(jì)、畢業(yè)設(shè)計(jì)乃至就業(yè)深造等打下牢固的實(shí)踐基礎(chǔ)。課程效果一般，對(duì)學(xué)生缺乏吸引力、不能激發(fā)學(xué)習(xí)興趣、學(xué)生個(gè)性和創(chuàng)新能力將得不到彰顯，教學(xué)目標(biāo)不能達(dá)成。……
