The necessary and sufficient condition on the impulse response for stability is:

The minimum rate at which a signal can be sampled and still be reconstructed from its samples is known as:

Find the ROC of the signal x(t), Given x(t) = [2e^-4t u(t) – 4e^-2t u(-t)]

A system with x(t) input and y(t) output is defined by the input-output relation: y(t) = conjugate symmetry [x(t)]. The system will be
