D. r<0
Answer:A
What is the condition for a signal x(n)=Brn where r=eαT to be called as an decaying exponential signal?
A. 0<r<∞ B. 0<r<1 C. r>1 D. r<0
Explanation: When the value of ‘r’ lies between 0 and 1 then the value of x(n) goes on decreasing exponentially with increase in value of ‘n’. So, the signal is called as decaying exponential signal.
