DAY 7

In this lab, we guess what the Vout will be when we have different Vin.

We guess the shape between Vin and Vout are same, but the amplitude will be different.

In the beginning of the lab, we are going to measure two resistors' true value. 

experiment set up. 

This is a sin wave. The frequency and period are same, but the amplitude is half.

This is a triangular wave. The frequency and period are same, but the amplitude is half

This is a square wave.  The frequency and period are same, but the amplitude is half.

In this lab, we are going to learn relationship between the collector current, IC and collector voltage.

  We are going to connect one 100K ohm resistor, one 100 ohm resistor, and a small signal NPN transistor in a breadboard,

Measured one 100 ohm resistor is 99.5 ohm
Measured one 100k ohm resistor is 99.4k ohm

 Experiment set up

The first input wave (top one). 
The second input wave (bot one).IMG 0446
  
The picture shows that oscilloscope of the wave it detected.
We can see that Ic vs Vce have 5 curves.
