B. Adder
C. Subtractor
D. Multiplier
Answer:A
If the output of the system is with an input of x(n) then the system will work as:
A. Accumulator B. Adder C. Subtractor D. Multiplier
Explanation: From the equation given, y(n)=x(n)+x(n-1)+x(n-2)+…. .This system calculates the running sum of all the past input values till the present time. So, it acts as an accumulator.
