This is a two stage transistor amplifier with a provision for positive and negative feedback. The amount of feedback is adjustable and with the help of this, it is even possible to make the amplifier oscillate. A 9V stabilized power is provided on the same board.
The following studies can be carried out with this set-up
- Study of the basic circuit of a RC Coupled Amplifier
- Frequency response of RC Coupled Amplifier
- Effect of negative feedback on the gain and frequency response of the amplifier
- Effect of positive feedback on the gain and frequency response of the amplifier
- Verification of the condition of oscillation
- Study of different classes of amplifier
Measuring/Testing Instruments required
The above experimental set-up has been laid down on a decorated bakelite board with an aim of providing an easy understanding to the students. All components are well spread out for clarity and easy repairs and replacement. The set-up is provided with a booklet, which contains its detailed theory of operation, description, specifications, suggestions and discussion on the various experiments that may be performed with it.
