how do u implement statistical average for a sinusoid
i want to implement process
where alphan is 1 by N random mumber
Ts= sampling period.
phin is again random number 1 by N
after summation i get y as 1 by Ns RV which is as expected. Bu tthis
is just a one sample. its mean is 0 and variance turns out to be
but due to random nature, we should have ensemble avg
i believe this is how ensemble calculated
but why does variance change... should it change and if yes how to get
variance 0.5 as a single sample...
