<p>System Requirements</p>
<p>Simcir requires a browser or Java Runtime Environment that support Java1.1.<br />
Successfully tested on following environment.</p>
<p>    * Sun JDK/JRE 1.1.7, 1.2.1<br />
    * Netscape Communicator 4.08, 4.5<br />
    * Microsoft Internet Explorer 4.01 SP1, 5.0</p>
<p>Usage</p>
<p>   1. Choice a device from the toolbox and move to right side.<br />
   2. Connect them by drag operation.<br />
   3. Click a input node to disconnect.<br />
   4. Move a device back to the toolbox if you don&#8217;t use.<br />
   5. Double click the label to edit.</p>
<p>Note</p>
<p>    * To simplify the model, all devices transfer only voltage but current.<br />
    * Please don&#8217;t make infinity loop like a vibrator. <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /><br />
    * When logic gate&#8217;s input node is not connected, it treated as pulled down.</p>

			<content:encoded><![CDATA[<div class='snap_preview'><br /><p>Mạch dao động được ứng dụng rất nhiều trong các thiết  bị điện tử, như mạch dao động nội trong khối RF Radio, trong bộ kênh Tivi mầu, Mạch dao động tạo xung dòng , xung mành trong Ti vi , tạo sóng hình sin cho IC Vi xử lý hoạt động v v…<br />
Mạch dao động được chia là hai loại :<br />
-	Mạch tạo dao động hình sin<br />
-	Mạch tạo xung : gồm xung vuông và xung tam giác<br />
Mạch tạo xung vuông<br />
•	Mạch dao động đa hài<br />
<img src="http://sanchoituoitre.vn/wp-content/uploads/2009/02/daodongdahai1.gif" alt="Mach da hai" /><br />
Mạch dao động đa hài tạo xung vuông</p>
<p>* Bạn có thể tự lắp sơ đồ trên với các thông số như sau :</p>
<p>    *      R1 = R4 = 1 KW<br />
    *      R2 = R3 = 100KW<br />
    *      C1 = C2 = 10µF/16V<br />
    *      Q1 = Q2 = đèn C828<br />
    *      Hai đèn Led<br />
    *      Nguồn Vcc là 6V DC</p>
<p>      Tổng giá thành lịnh kiện hết khoảng 4.000 VNĐ</p>
<p>•	Mạch dao động dùng IC</p>
<p><img src="http://sanchoituoitre.vn/wp-content/uploads/2009/02/osc_555.gif" alt="IC 555" /></p>
<p>    *      Bạn hãy mua một IC họ 555 và tự lắp cho mình một mạch tạo dao động theo sơ đồ nguyên lý như trên.<br />
    *      Vcc cung cấp cho IC có thể sử dụng từ 4,5V đến 15V , đường mạch mầu đỏ là dương nguồn, mạch mầu đen dưới cùng là âm nguồn.<br />
    *      Tụ 103 (10nF) từ chân 5 xuống mass là cố định và bạn có thể bỏ qua ( không lắp cũng được )<br />
    *      Khi thay đổi các điện trở R1, R2 và giá trị tụ C1 bạn sẽ thu được dao động có tần số và độ rộng xung theo ý muốn theo công thức. </p>
<p>T = 0.7 × (R1 + 2R2) × C1<br />
T = Thời gian của một chu kỳ toàn phần tính bằng (s)<br />
f = Tần số dao động tính bằng (Hz)<br />
R1 = Điện trở tính bằng ohm (W )<br />
R2 = Điện trở tính bằng ohm ( W )<br />
C1 = Tụ điện tính bằng Fara ( W )</p>
<p>T = Tm + Ts<br />
T : chu kỳ toàn phần<br />
Tm = 0,7 x ( R1 + R2 ) x C1 Tm : thời gian điện mức cao<br />
Ts = 0,7 x R2 x C1<br />
Ts : thời gian điện mức thấp</p>
<p>Chu kỳ toàn phần T bao gồm thời gian có điện<br />
mức cao Tm và thời gian có điện mức thấp Ts</p>
<p>    *      Từ các công thức trên ta có thể tạo ra một dao động xung vuông có độ rộng Tm và Ts bất kỳ.<br />
    *      Sau khi đã tạo ra xung có Tm và Ts ta có T = Tm + Ts và f = 1/ T</p>
<p>* Thí dụ bạn thiết kế mạch tạo xung như hình dưới đây.</p>
<p>Mạch tạo xung có Tm = 0,1s , Ts = 1s</p>
<p>Bài tập : Lắp mạch dao động trên với các thông số :</p>
<p>    *      C1 = 10µF = 10 x 10-6 = 10-5 F<br />
    *      R1 = R2 = 100KW = 100 x 103 W<br />
    *      Tính Ts và Tm = ? Tính tần số f = ?</p>
<p>Bài làm :</p>
<p>    *      Ta có Ts = 0,7 x R2 x C1 = 0,7 x 100.103 x 10-5 = 0,7 s<br />
      Tm = 0,7 x ( R1 + R2 ) x C1 =<br />
      = 0,7 x 200.103 x 105 = 1,4 s<br />
    *      =&gt; T = Tm + Ts = 1,4s + 0,7s = 2,1s<br />
