How to shift summation
WebMar 22, 2024 · A passage from discrete to continuous would go something like this: Say we're talking about the normalization of a probability mass function: 1 = ∑ n = 0 N W ( n). You first note that n is a counting number, so its increments are by 1. Namely, d n = 1. So you can just insert one: 1 = ∑ n = 0 N d n W ( n). WebThen, by the commutativity of addition, the order of the values appearing in the sum doesn't matter, so the two sums can be taken to be equal. Then it is a matter of seeing that if $0 \leq k \leq n$ defines the same set as $0 \leq n-k \leq n$, which we can see as follows:

WebNov 16, 2024 · Performing an index shift is a fairly simple process to do. We’ll start by defining a new index, say i i, as follows, i =n −2 i = n − 2 Now, when n = 2 n = 2, we will get i = 0 i = 0. Notice as well that if n = ∞ n = ∞ then i = ∞−2 =∞ i = ∞ − 2 = ∞, so only the lower limit will change here. Next, we can solve this for n n to get, n =i +2 n = i + 2
WebJan 3, 2015 · We may change the index of summation from r to s=r+k. Then because r starts from m, s should start from m+k and because r ends at n, s should end at n+k.
