5Obrac fzi, proudov a napov zeslen je mnohem vt ne 15 Components Value T NPN ( BC 548 ) R1 M1 R2 10K R3 470 R4 4K7 C1, C2 1M/16V C3 20M/16VComponents specification
6 Quantity Value Input resistance ( RVST ) small - medium ( 100ohm 10k ) Output resistance ( RVST ) big ( 1k 100k ) Voltage amplification ( AU ) big ( 10 1000 ) Current amplification ( Ai ) Very big ( 20 200 ) Efficiency amplification ( AP ) Very big ( 100 20 000 )Properties of connection of amplifier with SE
7Design connection of amplifier with common emitter on the cuprexite board.Take measurement of components on own measure device and solder it together .Activate the amplifier.Evaluate your work.
Practical part of assigned task
8What voltage we can measure on transistor electrode ?How big electric current passing through the circuit ?Calculate amplification of amplifier AU.Calculate gain of amplifier in dB. Evaluate your work.Students activities- control questions
