Study of Direct Coupled Amplifier and its frequency response with power supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12237
Indian Lab Suppliers supplies the Study of Direct Coupled Amplifier and its frequency response with power supply (Product ID: 12237) as part of its electronics engineering lab equipment range. It is a training board for measuring the gain and frequency response of a two-stage direct-coupled transistor amplifier.
Quick Answer
Students build the two-stage amplifier from the two on-board transistors, measure its voltage gain and then plot gain against frequency. With no coupling capacitors between stages, the response extends down to very low frequencies, which the curve makes clear. A 12 V DC, 30 mA IC-regulated supply is connected internally. An audio frequency generator, an AC millivoltmeter and a 20 MHz oscilloscope are required.
