◆ 更新內容：在與命題老師再次確認後，得到更新後之正確解如下！第二題(1) y=0, and (2) the voltage change due to charge sharing is also 0 ◆ 說明： 1. 助教將於今明兩日送成績前針對第二題部份重新批閱，然而，電路有錯而得到XOR解之同學，分數將會重新計分，而重新批閱後之成績會於批閱完成之後，推文於該公告中。 2. 另外，關於第五題之其他兩種解法，目前正在與命題老師討論中，若是有更新的話，會一併將以該種解法而應給分數的同學之成績一併計入，謝謝。 ◆ 備註：檢附老師的回信內容，以茲證明。 ============================================================================= ----- Original Message ----- From: xxxx To: xxxx Sent: Wednesday, January 18, 2012 12:18 PM Subject: Re: 電子學(三)期末考試題與解答 There is a mistake in the original figure on the textbook where the short line above node b should be taken off. It is not your fault. So the actual answer in our final exam is (1) y=0, and (2) the voltage change due to charge sharing is also 0. Please recorrect the exam accordingly and let them know.
