#### Circuit Description
The circuit contains two identical transistor amplifier stages. Each stage consists of the following components:
1. **Power Supply**:
- The circuit is powered by a single +15V DC supply.
2. **Transistor Parameters**:
- The transistors used have a current gain, \( \beta \) = 100.
3. **Resistors**:
- Each stage contains multiple resistors as follows:
- \( 10 \text{k}\Omega \) resistor is connected from the collector to the positive power supply.
- \( 2 \text{k}\Omega \) resistor is connected between the base and the ground.
- \( 5 \text{k}\Omega \) resistor is connected in series with the input signal.
- Additionally, a \( 2 \text{k}\Omega \) resistor is connected between the emitter and ground.
4. **Capacitors**:
- Capacitors are used for coupling and bypassing:
- \( C_{in} \) couples the input signal to the base of the first transistor.
- Another capacitor couples the collector of the first transistor to the base of the second transistor.
- A capacitor is also placed in parallel with the \( 2 \text{k}\Omega \) emitter resistor in each stage.
5. **Input and Output**:
- The signal is input at the left extreme of the circuit.
- The output is taken from the collector of the second transistor stage and is coupled out through a capacitor.
#### Diagram Explanation
The diagram above shows a two-stage transistor amplifier with the following flow:
1. **Input Stage**:
- The input SIGNAL is fed through the \( 5 \text{k}\Omega \) resistor to the base of the first transistor.
- \( C_{in} \) is the coupling capacitor ensuring only the AC signal component is passed to the base of the first transistor.
2. **First Transistor Stage**:
- The first transistor amplifies the signal. The collector resistor \( 10 \text{k}\Omega \) is connected to the 15V power supply, and there](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3d6fa171-8a96-4a91-bca7-267628414860%2F55e1bb58-f0c4-43f6-9a09-766e1c13985f%2F3rtrk3_processed.jpeg&w=3840&q=75)
