Dear Engr. Cunanan,
Attached is the report entitled “Operation and Application of a Bipolar Transistor”. The report discusses how a bipolar transistor is operated and applied as a circuit element in the electronics and communication devices.
In this report, the circuit element involves three types of connections – the common emitter, the common base, and the common collector. These elements apply to different kinds of electronic and communication devices which utilize the bipolar transistor.
Truly yours,
Anselmo de Guia
General Manager
