Here is my task and solution for a)
Any suggestion for task b) ?
What your thought about this ? Also do you recognize the building blocks?
When v12(t) reaches in amplitude value of VD+VZ=6.8V, DZ1 will start conducting in forward direction DZ2 will start conducting in reverse direction. While conducting, they will provide constant voltage drop on R, 6.8V.
That's what I know
The two top circuits are called All-Pass filters, as their ouput phase changes with frequency but the amplitude is constant.
At first glance the answer looks obvious. But to by honest the more I think about it, the more confused I get. So I don't know how you can find this output voltage.
This is very strange example I would say Even simulation in Multisim show result which I would not expect.
I got the attached results in a simulation. There was NO VD in your diagram. I did set an initial charge on the capacitors to kickstart the oscillations. Post your multisim.
R5 in your schematic should be 10k
I will post multisim
I followed your R2 < R3 instruction in b)
I will change it back to 10 k and rerun the simulation and post the results
