In an effort to digitize an analog signal Y(t), we would like to select the right sampling rate for the following signal: Select the right sampling rate for this signal.

( What will happen if the sampling rate from the above answer (a), is used to sample the following signal Y= 3sin(250r)t. (10 points) ) Discuss if Aliasing is happening for answer (b) and if yes why? What will be the observing Aliasing Frequency? (10 points) Y(t)=4 \sin (25 \pi) t+4 \sin (75 \pi) t
