Product Code : SCL-EELE-12323
Indian Lab Suppliers supplies the Feedback Amplifier (4 Types Using Transistors) (Product ID: 12323) as part of its electronics engineering lab equipment range. It holds four transistor amplifiers wired for the four negative-feedback types: current series, voltage series, voltage shunt and current shunt.
Quick Answer
Each of the four independent amplifiers has a toggle switch that connects or removes its feedback, so students can measure gain, bandwidth and input and output impedance with and without feedback. Negative feedback lowers gain but widens bandwidth and steadies the gain; series feedback raises input impedance, shunt feedback lowers it, voltage feedback lowers output impedance and current feedback raises it. Six NPN transistors are used, powered from a 12 V DC, 100 mA IC-regulated supply. An audio frequency generator and a dual-trace 20 MHz CRO are required.
