Creation of Triangle Waveform and Circuit Analysis with Laplace Transformation

Creation of Triangle Waveform and Circuit Analysis with Laplace Transformation

Hello Guys!

 

I want to analyse my circuit, using laplace transformation.

 

Step 1) First I have to generate a triangle waveform.

I have all informations given like peak-value, duty cycles, frequency, and so on.

I could obtain a triangle waveform by defining sections with the if-equation, according to the post from Werner:

https://community.ptc.com/t5/PTC-Mathcad/Plots-for-Conditional-Function/td-p/124048

 

My first idea was to multiply a sawtooth function with a rect function, but nevermind. I keep the solution from Werner I guess if the following Step 2) will work...

 

Another approach would be a fourier row to obtain the triangle shape. Maybe you have some older work / examples here for me?

 

Step 2-4) I want to make a Laplace Transformation from the triangle waveform, means: i(t) -> I(s)

 

--> is it posible with my function from Step 1) to do a laplace transformation, or do I have to go the approach with fourier rows?

 

(Step 3) Vout(s)=I(s)*G(s), with G(s) = Transfer-function of a circuit

 

(Step 4) Inverse Laplace Transformation Vout(s) -> vout(t) and plot

 

I am working with Prime 3.0

 

Best Regards

Please (please please) attach your Prime worksheet. And state your problem (if any)..

 

Success!
