What is the nature of the following function: y[n] = y[n-1] + x[n]?
A. Integrator B. Differentiator C. Subtractor D. Accumulator
Explanation: If the above recursive definition is repeated for all n, starting from 1,2.. then y[n] will be the sum of all x[n] ranging from 1 to n, making it an accumulator system.
