Question
Ques. 11. Input x(t) applied to an inverting op-amp follower circuit
produces output y(t) according to
-Vref
x(1) > Vref
x(t) < –Vref
otherwise
y(t+tp) =
Vref
-x(t)
where op-amp reference voltage Vref and propagation delay t, are both
positive constants. Answer the following questions with YES or NO and
provide mathematical justification for each answer.
(d) Is the system linear?
(e) Is the system memoryless?
(f) Is the system time-invariant?
It is already known that the system is BIBO stable, the
system is causal, and that the system is non-invertible.
