Introduction and Basics of Electronic Circuit Design                                          

Designing an electronic circuit begins on the breadboard (protoboard). The bed board is a thin plastic rectangular construction base to which electronic components are soldered. The soldered connections are not permanent and can be removed and placed again and again within reason. The construction of a breadboard subsequently turns it into what is known as a PCB, often used in computations, signal amplification, and data transfer.

The interconnections on a PCB connect the soldered components. Charge flows from the positive terminal throughout the interconnection loops to the negative terminal.

Note, Q3 and Q4 in the figure below are complementary, NPN and PNP respectively. This circuit works well for moderate power audio amplifiers. For an explanation of this circuit see “Directly coupled complementary-pair,”
