“Since you have posted a question with multiple sub-parts, we will solve first three sub-parts for you. To get remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.”.
The system function is given below,y[n] = sin nxn-1+1
Part (a). Memory/Memoryless system -
In the given system function,
The current values is dependent on the past values. so, the system is a memory system.
Part (b). Causal/Non-causal system -
It is also a causal system because it is a memory system with current value that are dependent on earlier input data.
Part (c). Stable/Unstable system -
We know that the sine value is a bounded function.
Here, the provided system function is also bounded.
As a result, it is also a BIBO stable system.
