A coin and a die are rolled. The sample space(S) of getting a Head(H) on the coin and an even number on the die is: => S = { (H, 2) (H, 4) (H, 6) (T, 2) (T, 4) (T, 6) } or S = { (H, 2) (H, 4) (H, 6) } or S = { (H, 1) (H, 2) (H, 3) (H, 4) (H, 5) (H, ..

It is the time taken by the particle executing SHM, to complete one oscillation i.e., a to and fro motion. It will be equal to the time taken by the body to complete one revolution or the circle of referen..

refers to the process of taking instantaneous values of the message signal at regular intervals (in the case of uniform sampling.) This makes the time-frame (of the analog signal) discrete. Most pulse systems are based on sampling of the information signal amplitude at periodi..
