Day fifteen - Inverting Differentiator 4/25/2017

Hello guys, today we briefly talked about integrator and differentiator. They are some variations of inverting op-amp.

After that, we talked about the step function, impulse function, and ramp function.
For simplification, impulse is the derivative of step function and ramp is the integration of step function.

Step function is called step function because it is either 0 or 1. (of course can multiply something)
Impulse function is called impulse function because it is approaching infinity when the step function suddenly put the voltage from 0 to 1.
Ramp function is called ramp function because the voltage is constant.

Pre-Lab

This is our pre-lab result.

Here is the schematic and the actual resistance.

Result

This is with 100hz

This is with 250 hz

This is with 500 hz

Here is the result showing the value.

Summary:
Today lesson, I learned about the step, impulse, and ramp function which can be applied to real circumstances when there are sudden change. I also learned how to implement a differentiator, and the result is very reliable comparing to the measured value.
