A buffer amplifier is a cathode follower double tuned amplifier.

A buffer amplifier is a cathode follower double tuned amplifier. Correct Answer False

Gain of an amplifier is it’s ability to increase the voltage at the input and produce the result at the output. A buffer amplifier is basically a high gain DC amplifier. It is basically used for transferring voltage from a high output impedance level to a low input impedance level circuit.

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?
Statement (I): When a flat-faced follower is used, it would be preferable to provide an offset in the plane perpendicular to the plane of rotation of the cam. Statement (II): Because of the offset, the follower is made to rotate continuously about its axis which in turn avoids jamming of the follower in its guide while moving up or down, reduces the wear of the follower flat surface and distributes the wear uniformly.
The displacement and velocity diagrams of a cam and follower mechanism are shown as: Which of the following statements is/are correct? 1.

During period DE, the motion of the follower is retarding. Select the correct answer using the code given below.
