Transistor Amplifier Demonstrator Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12342
Indian Lab Suppliers supplies the Transistor Amplifier Demonstrator (Product ID: 12342) as part of its electronics engineering lab equipment range. It is a board for measuring the performance of a common-emitter transistor audio amplifier.
Quick Answer
Students measure voltage gain, plot the frequency response and find the input impedance, output impedance, current gain and power gain of a single CE stage. The amplifier uses a PNP transistor powered from a built-in -9 V DC, 50 mA IC-regulated supply, which is why the rail is negative. A signal generator and an oscilloscope are needed for the gain and frequency-response readings.
