Memoryless Systems
- These are systems whose output signals only depend upon input signals at the specific time. These systems do not depend upon the past input signal, nor the future.
Systems which ARE memoryless are: y(t) = x(t) y[n] = 2x[n] - 1
Systems which ARE NOT memoryless are: y(t) = x(t-1) y[n] = 2x[2n]
