Experimentation with BJT Amplifiers and Emitter Follower 

BJT Experimentation with Amplifiers and Emitter follower is a unique product designed to explain the role of BJT as Single Stage/Multistage RC-coupled Amplifiers and as a Common Collector Emitter Followers. One of the most common methods for coupling two stages of an amplifier is RC-coupling. RC-coupled amplifiers have the advantage of wide frequency response and a relatively small cost and size. Darlington Transistors are circuits that combine two bipolar transistors in a single device such that high Current Gain (b) is obtained and lesser space is required than that used by two discrete transistors. BJT Experimentation with Amplifiers and Emitter is useful for students In plotting the Frequency vs. Gain Response of BJTs and in the measurement of parameters such as Bandwidth, Input Impedance etc.
