Product Code : SCL-EELE-12112
Indian Lab Suppliers supplies the BJT Amplifiers and Emitter Follower Trainer (Product ID: 12112) as part of its electronics engineering lab equipment range. It is a trainer for single-stage and multistage RC-coupled BJT amplifiers and Darlington emitter-follower circuits.
Quick Answer
Students study single-stage and multistage RC-coupled amplifiers and plot gain against frequency to find the bandwidth. The emitter-follower section uses a Darlington pair, two transistors combined for a very high current gain, to measure its current gain and input impedance, the β of a single transistor, and the Darlington voltage gain with voltage-divider bias. A built-in sine generator (10 Hz–100 kHz ±10%, 0–5 Vpp) and +12 V and +5 V DC supplies are included. It runs on 230 V ±10%, 50 Hz, with a 500 mA slow-blow fuse.
