The first one deals with the currents in the circuit: 51At any point in the circuit the sum of currents flowing in is equal to the sum 52of currents flowing out. 1. For any node of the circuit P in I = P out I. Note that the choice of in" or out" for any circuit segment is arbitrary, but it must remain consistent. So for the example of Fig. 2 we have I 1 = I 2 +I 3. 2. For any closed circuit, the sum of the circuit EMFs (e.g. batteries, generators) is equal to the sum of the circuit voltage drops: P E • Analysis and design of electronic circuits. 1.2 Content of This Course • Electric circuit (Passive Circuit ) analysis. — Only containing Resistor (U), Capacitor (F), and Inductor (O). — No signal amplification. • Electronic circuit (Active Circuit ) analysis. — Containing transistor. — Single transistor circuit. — Signal Electric Circuits I "Dr. Ahmed El-Shenawy" Two elements are in series if the current that flows through onemust also flow through the other. R1 R 2 Series If we wish to replace the two series resistors with a single equivalentresistor whose voltage-current relationship is the same, the equivalentresistor has a value given by Req R1 R2 OBJECTIVES: EC8452 Notes Electronic Circuits 2. To give a comprehensive exposure to all types of amplifiers and oscillators constructed with discrete components. This helps to develop a strong basis for building linear and digital integrated circuits. To study about feedback amplifiers and oscillators principles. To design oscillators. circuit is zero. So the output voltage vout= VR=0 For high frequency since capacitor is short circuited, So the output voltage vout= VR= vin The frequency response curve can be shown as below Calculation of cutoff frequency: vout= R XC R + vin vout = 2 C2 C R X X + vin If R=Xc Vout= 2 1 v in=0.707 vin At the frequency of which R=Xc, the output Tables 9.13-1, 2, and 3.
