1.	If x(t-5)=0 for t=5, the signal is ___________(a) Causal(b) Symmetric(c) Linear, Time Invariant and Causal(d) Cannot be determinedI have been asked this question during an online interview.This interesting question is from Operations on Signals topic in portion Digital Signal Processing of MATLAB
Answer» Right option is (a) CAUSAL For explanation I would say: The signal given to us is delayed by 5 units in time. If we advance the signal by 5 units, the signal AMPLITUDE is 0 for t<0 but A for t>=0. Hence, the signal will be causal.
