Description

1. Study provided an amplifier circuit.
2. Locate the desired pattern on the circuit all local and general feedback specify the elements of these chains.
3. Describe the feedback circuit R4, R5, C2, C3, C4 on the plan:
- The sign;
- The frequency dependence;
- The type of the transmitted signal;
- On the method of administration;
- By the method of removal.
4. Explain how this feedback on the performance of the amplifier:
- On the value of the gain;
- On the linear, frequency, and phase distortion;
- On non-linear distortion;
- The stability of the gain;
- On the input impedance;
- The output resistance.

Additional information

Characteristic feedback circuits two-stage amplifier transistors and influence on the parameters of the feedback amplifier.
