Q349
Let P be linearity, Q be time-invariance, R be causality and S be stability. A discrete-time system has the input-output relationship, \[y ( n ) = \ array*20c x ( n ),&n 1 \\ 0,&n = 0 \\ x ( n + 1 )&n - 1 array .\] Where x(n) is the input and y(n) is the output. The above system has the properties
Let P be linearity, Q be time-invariance, R be causality and S be stability. A discrete-time system has the input-output relationship,
y\left( n \right) = \left\{ {\begin{array}{*{20}{c}} {x\left( n \right),}&{n \geqslant 1} \\ {0,}&{n = 0} \\ {x\left( {n + 1} \right)}&{n \leqslant - 1} \end{array}} \right.
Where x(n) is the input and y(n) is the output.
The above system has the properties
y\left( n \right) = \left\{ {\begin{array}{*{20}{c}} {x\left( n \right),}&{n \geqslant 1} \\ {0,}&{n = 0} \\ {x\left( {n + 1} \right)}&{n \leqslant - 1} \end{array}} \right.
Where x(n) is the input and y(n) is the output.
The above system has the properties
