The discrete time function defined as u(n)=n for n≥0;=0 for n<0 is an:
A. Unit sample signal
B. Unit step signal
C. Unit ramp signal
D. None of the mentioned
Answer:A
The discrete time function defined as u(n)=n for n≥0;=0 for n<0 is an:
A. Unit sample signal B. Unit step signal C. Unit ramp signal D. None of the mentioned
Explanation: When we plot the graph for the given function, we get a straight line passing through origin with a unit positive slope. So, the function is called as unit ramp signal.
