Q226
Consider a single input single output discrete-time system with x[n] as input and y[n] as output, where the two are related as \[y [ n ] = \ array*20c n | x [ n ] |,& for 0 n 10 \\ x [ n ] - x [ n - 1 ],& otherwise array .\] Which one of the following statements is true about the system?
Consider a single input single output discrete-time system with x[n] as input and y[n] as output, where the two are related as
y\left[ n \right] = \left\{ {\begin{array}{*{20}{c}} {n\left| {x\left[ n \right]} \right|,}&{{\text{for }}0 \leqslant n \leqslant 10} \\ {x\left[ n \right] - x\left[ {n - 1} \right],}&{{\text{otherwise}}} \end{array}} \right.
Which one of the following statements is true about the system?
