please I need help

[pink]

Hi
please if you can help me?
I have this circuit
The question is:
Discuss the name and the number of the the stages of the the amplifier circuit?

 

[technogeek]

sounds suspiciously like homework

 

[dknguyen]

Stage 1- amplifies input signal

 

[audioguru]

It uses an awful lot of batteries for such a simple circuit.

 

[RadioRon]

Looks an awful lot like like homework.

 

[Nigel Goodwin]

Still looks like homework! - and the diagram doesn't make much sense anyway!.

 

[pink]

I need to know for each BJT if it's:
common source, common emiter or common base

 

[audioguru]

A BJT doesn't have a source and doesn't have an "emiter".
A field-effect transistor has a source, which is something like an emitter.

Lookup Transistor in Google or in your textbook. Ask your teacher to teach it again.

where is this circuit used?
