Hello
here was my exam question which I couldn't solve.
can someone help me please?
according to the picture in attachment:
a- a) What is the U_eff, duty cycle?
b- b) How should be the properties of Wave Generator, Prescaler, OCR so that we have such signals?
c c) How to get the inverse of such a signal?
d- d) How can we have duty cycle of 20%?
e- e) what can happen to OCR and Wave Generator if we ignore f_in?
I could just solve part a which I am not sure if it is correct or not.
a)
Duty Cycle: 29,5/(29,5+49,5)= 0,421
U_eff: 5*0,421= 2,105
It would be great if someone can really good explain the answers.
Thanks in advance
best regards,
frhling
Ps.:Sorry I forgot to change two words: Höhenzahl= High, Niederzahl= Low
