I have a very confusing teacher for my electronics lab, I am suppose to design an astable multivibrator with an output frequency of 5KHz and a duty cycle of 70% using a 555 timer.
Thats what I'm suppose to do in lab I have the following pre-lab questions that I can't find information for...
What is the period of the output signal? Give your answer in microseconds.
I have this formula T= 0.693 [(Ra+2Rb)C1] am I suppose to use the following frequency formula to find the values of Ra, Rb and C1. f0=1.44/(Ra+2Rb)C1 if so I don't understand.
The other questions have to deal with how long should the high be for each cycle and how long with the low be for each cycle, I can't even find a formula for that in my textbook.
Any help would help. Thanks
