Regenerative Amplifier (V.V.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12151
Indian Lab Suppliers supplies the Regenerative Amplifier (V.V.) (Product ID: 12151) as part of its electronics engineering lab equipment range. It is a vacuum-valve training board for studying an amplifier with positive (regenerative) feedback.
Quick Answer
A valve is mounted on the panel and two band switches select different resistance values to set the amount of positive feedback. Students compute the gain without feedback and with several feedback values, and draw the frequency response in each case. With positive feedback the gain rises as A/(1 − βA) while the bandwidth narrows, and the stage becomes unstable as βA approaches 1. An external regulated supply is required; its voltages, the valve type and the board size are not stated, so please confirm at quotation.
