Product Code : SCL-EELE-12170
Indian Lab Suppliers supplies the Transistor Feed Back Amplifier with power supply and 1KHz Oscillator (Product ID: 12170) as part of its electronics engineering lab equipment range. It is a training board for studying how negative feedback changes the gain, impedances and overload behaviour of a two-stage transistor amplifier.
Quick Answer
The board carries a two-stage transistor amplifier, a fixed 1 kHz solid-state sine oscillator with 0–1 V output control, and an external feedback network of ten resistors selected by a band switch with a fixed feedback capacitor, all run from a 9 V DC, 100 mA IC-regulated supply. Students measure gain at 1 kHz with and without emitter feedback, then with different amounts of external feedback, and measure input and output impedance and overload characteristics. Negative feedback lowers the gain to A/(1 + βA) but widens bandwidth and reduces distortion.
