Question

Find the Z transform of a constant'a'.​

Answer 1

Answer:

Z transform of any constant is considered non-exsisting. But a certain can be taken, like r(n)=a|n| can be taken as function and by replacing a with 1 the function becomes constant. For such a function there is formula as R(z)=[(1−a2)/((1−az)(1−az−1))] And one can solve this by definition of z transform. For the solution z lies between a−1 to a . Hence by replacing a with 1 the solution is zero, doesn't exist.
