i really need some one to help me build, and understand the basic concept of a common emitter amplifier,and also if there are site that could help me understand better. Thankx
The common emitter amplifier is used to increase the voltage level of in put signal with small increment in current also but current gain is very less compare to common collector.
for learning biasing download Lt spice open source software.
The abbreviation 'cct' is often used to replace 'circuit'.
I do not use it any more because so many words are abbreviated in 'SMS-text speak', it can have many meanings.
