System Properties

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]

Invertible Systems

Causal Systems

Stable Systems

Linear Systems

Time-Invariant Systems

Alumni Liaison

Basic linear algebra uncovers and clarifies very important geometry and algebra.
