The ztransform of discrete time signal x[n] = {1, 0, 1,0, 1,1} is
A all pass causal LTI system is described by the difference equation:
y[n]  ay[n  1] = bx[n] + x [n  1]
The value of ’b’ will be
Consider a discrete time signal x(n) having ztransform given by if x(n) is right sided then ztransform x(z) belongs to
The sequence x[n] corresponding tox (z) defined as will have the value at n =  2
The direct.formII realisation of []R filter is shown below.
The transfer function is
A sequence of x(n) with the ztransform x(z) = z^{4} + z^{2}  2z + 2  3z^{4} is applied as an input to a L.T.I system with the impulse response where, the output at n = 2 is
