EDC Exam 2025: Important Questions Every Student Must Prepare
Are you preparing for ECE 303 (Electronic Devices and Circuits)? If haan, toh yeh blog aapke liye hai. Isme humne "EDC ka books pdf" notes ka analysis karke sabse important, conceptual, aur frequently asked questions ko list kiya hai, jise padkar aap apne exam ki preparation aur strong kar sakte ho.
1. Basic Semiconductor Concepts
- What is the difference between intrinsic and extrinsic semiconductors?
- Explain N-type and P-type semiconductors.
- Define depletion region and minority carriers.
Why important? Semiconductor basics har topic ka foundation hai.
2. Diodes and Applications
- Explain the V-I characteristics of a PN junction diode.
- Working of Zener Diode and its application in voltage regulation.
- What is a clamping circuit? Explain with circuit diagram.
- Clipping vs Clamping: With waveform explanation.
Exam Tip: Clipping and clamping circuits se diagram-based questions aate hain.
3. Transistors (BJT, FET)
- Biasing of BJT and Q-point concept.
- BJT configurations (CB, CE, CC) with characteristics.
- Explain FET as voltage variable resistor.
- Transfer characteristics of JFET.
- Pinch-off voltage and its significance.
Most Asked: CE configuration and biasing techniques.
4. Amplifiers and Feedback
- Classification of amplifiers.
- Feedback amplifier and its types.
- General characteristics of negative feedback amplifier.
- What is a power amplifier? Explain push-pull amplifier.
Pro Tip: Focus on advantages of negative feedback and amplifier classes (A, B, AB).
5. Oscillators
- What is an oscillator? Explain Barkhausen criterion.
- Difference between Hartley and Colpitts oscillators.
Trick: Hartley = tapped inductor, Colpitts = tapped capacitor.
