Option 2 : 𝑇 = 1.2 𝑇𝑠

A continuous time signal x(t) is periodic with period T and sampling period Ts.

As we know that , 

 sampling frequency f ≥ k fs 

So,

      Ts < T 

where, k is constant and it is integer.

Therefore, from the option ? = 1.2 ?? is valid.

Consider the following solution to the producer-consumer synchronization problem. The shared buffer size is . Three semaphores empty, full and mutex are defined with respective initial values of 0, and 1. Semaphore empty denotes the number of available slots in the buffer, for the consumer to read from. Semaphore denotes the number of available slots in the buffer, for the producer to write to. The placeholder variables, denoted by P, Q, R, and S, in the code below can be assigned either empty or full. The valid semaphore operations are: wait ( ) and signal ( ). Producer: Consumer: do {         wait (P) ;         wait (mutex) ;         //Add item to buffer         signal (mutex) ;         signal (Q) ; } while (1) ; do {          wait (R) ;          wait (mutex) ;          //Consume item from buffer          signal (mutex) ;          signal (S) ; } while (1) ;   Which one of the following assignments to P, Q, R and S will yield the correct solution?

In making decisions about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those, which are both important and directly related to the question. ‘Weak’ arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The questions below is followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is. Statement: Should capital punishment be removed Arguments: I. Yes. No person has the right to take someone else’s life. II. No. There are some gruesome cases and capital punishment should be given in these rarest of rare cases.  ?
