Two Stage Transformer Coupled Amplifier with power supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12184
Indian Lab Suppliers supplies the Two Stage Transformer Coupled Amplifier with power supply (Product ID: 12184) as part of its electronics engineering lab equipment range. It is a training board for studying a two-stage transistor amplifier with audio-transformer coupling between the stages.
Quick Answer
Two transistors and a set of audio transformers are powered by an IC-regulated −12 V DC, 50 mA supply. Students plot the frequency response, read off the lower and upper cut-off frequencies and the bandwidth, and compare the result with a two-stage R-C coupled amplifier. Transformer coupling gives good impedance matching and gain, but the transformer inductance and winding capacitance narrow the frequency response at both ends.
