Design of printed circuit from the side of components and circuits


Components specification


Instruction for construction of amplifier

Supply voltage is connected through filter member ( brum, oscillating )

Equipped by any kind of nf. transistors of BC type …

Printed circuit firstly equipped by R, than another components and by electrolytic condensers in the end .

Among condensers, resistances and printed circuit let a gap about 1 mm, influence of temperature on the printed circuit board.

Do not shorten terminal of the transistors.

Finally soldered resistance R2.


Entering to students- practical part

  • Realize connection of two- stage amplifier on the printed circuit board.

  • Individually design connection by the pattern from the side of the components and from the side of the circuit.

  • Take their measurement before soldering of components.

  • After soldered make recovery and measurement of amplifier.

  • Take measurement amplitude frequency characteristic of amplifier.


Control questions

  • Explain how is calculate amplification of amplifier ?

  • Calculate a gain of amplifier.

  • Compare volumes of two- stage amplifier with amplifiers SE, SB, SK and explain it.
