___________ is defined as the ratio of desired signal power to undesired noise power.

___________ is defined as the ratio of desired signal power to undesired noise power. Correct Answer Signal to noise ratio

SNR is defined as the ratio of desired signal power to undesired noise power, and so is dependent on the signal power. When noise and a desired signal are applied to the input of a noise less network, both noise and signal will be attenuated or amplified by the same factor, so that the signal to noise ratio will be unchanged.

Below a question is given with one passage and its effects (I) and (II). One of these effects or both or none may be the effect of the statement. Read both the effect and decide which of the following answer choice correctly depicts the relationship between these cause and effect. Passage: In the urban area there exist a lot of industries, commercial places and public places religious places which involve a lot of a  people and working machinery note of sound and when this sound becomes unpleasant it is known as noise. it is one of the reasons why public authorities have divided the city into a number of zones is known as a different noise level. Effects: I        Noise leads to emotional and behavioural stress. A person may feel disturbed in the presence of loud noise such as produced by heating of drums. II       Noise may cause damage to the liver, brain, and heart.

Consider the following statements regarding modulation : 1. The communication systems, where a weak signal is transmitted by the use of a modulation is essential in carrier signal. 2. When the frequency of the high frequency signal is varied in accordance with the intensity of the low-frequency weak signal, the modulation is said to be frequency modulation. 3. The process of recovering original baseband signal from the modulated signal is called phase modulation. Which of the above statements are correct ? 
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?
