Question 2: Write any four applications of electronics in the field of defense.

Answer:

• Electronic circuits provide a means of secret communication between the headquarter and different units
• RADAR that is Radio Detection and Ranging is the most important development in electronics field. With the help of radar, it is possible to detect and find the exact
  location of enemy aircraft, Radar and anti-craft guns can be linked by an automatic
  control system to make a complete unit

Question 3: How does an Avalanche breakdown differ from Zener break down?

Answer:

Zener break down	Avalanche breakdown
1.This occurs at junctions, which being heavily doped have narrow depletion layers.	1. This occurs at junctions which being lightly doped has wide depletion layers.
2. This breakdown voltage sets a very strong electric field across this narrow layer.	2. Here, electric field is not strong enough to produce Zener breakdown.
3. Here, electric field is very strong to rupture the covalent bonds thereby generating electron hole pairs. So even a small increase in reverse voltage is capable of producing large number of current carriers, i.e. why the junction has a very low resistance. This leads to Zener breakdown	3. Here, minority carriers collide with semiconductor atoms in the depletion region, which breaks the covalent bonds and electron-hole pairs are generated. Newly generated charge carriers are accelerated by the electric field, which results in more collision and generates avalanche of charge carriers. This results in avalanche breakdown.

Question 4: What is the working principle of SMPS?

Answer:

SMPS means switch mode power supply. This works on the principle of switching regulation. The SMPS system is highly reliable, efficient, noiseless and compact because the switching is done at very high rate, in the order of several KHz to MHz.

Question 5: Describe the role of different capacitors in RC coupled amplifier.

Answer:

• Coupling capacitor CC is used to connect the output of first stage to the base, i.e. input of the second stage and this continues when more stages are connected. The coupling capacitor CC transmits AC signal but blocks DC.
• This prevents DC interference between various stages and the shifting of operating point. The emitter bypass capacitor offers a low resistance path to the signal. Without this capacitor the voltage gain of each stage would be lost.
