Other Parts Discussed in Thread: TIDA-01063
Hi, this is a beginner's question.
I studied TIDA-01063 design guide. I want to use the rogowski coil in my product. The question is when I implement the digital integrator, I need to turn this equation into c code.
y(n) = y(n-1) + T*x(n)
x(n) is the input data. y(n) is the output data. But, at first time, where can I get the y(n-1)?
In the excel included in the TIDA-01063, I found the first y(n-1) is 0. Is this always true?
In my application, sometimes the ADC will halt, which means the integrator stop. When the ADC works again, the value of y(n-1) is random, because I don't know when previous integration happened. At this time, what value I should assign to the y(n-1).
This is a beginner's question. Thank you.
