Day 18 Transistor

Transistor and amplifier

We were asked to build a electric circuit~!!

With above setup and amplifier 3kHZ, frequency 0.3 V with 2N3904 transistor, we got the graph below.

Here comes two waves by function generator.

It shows original V as 0.3 V and another one above with 20V~30V.

It means the set up one has 100 times bigger than original.

Semiconductor Lab:

Using the graph above to set up the circuit.

This is the setup we finally be able to here the music
