Hi,

I require some help creating a 2point moving averager using only flipflops and adders (no digital signal processing). I need to implement this into my project any help will be much appreciated.

many thanks

 

How would you calculate the average of two numbers?

 

And, once you consider how to add two numbers, the next thing you need to do is consider what, mathematically, a "two-point moving average" means.

In particular, if you have

x[0] The present input data value
x[-1] The previous input data value
x[-2] and so on...
x[-n]

and

y[-1] The last output of the system
y[-2] The one before that
y[-n] and so on...

What would be an expression for the new output, y[0].
