The dominating effect of thermal noise over the shot noise in photodiodes without internal gain can be observed in wideband systems operating in the range of ________ Correct Answer 0.8 to 0.9 μm

When the photodiode is without internal avalanche gain, the detector load resistor and active elements’ thermal noise in the amplifier tends to dominate. It is seen in wideband systems operating in the 0.8 to 0.9 μmwavelength band. This is because the dark currents in the silicon diodes can be made very small.

Amar and Baron are given a six-shot pistol that has only one bullet in its cylinder. Both of them fire a slot one after the other. A shot can be a black shot or a lethal shot. The one, who fires a lethal shot, is the winner. After each shot, the cylinder of the pistol is shuffled so that the other person has a fair chance of firing a lethal shot. It is also known that Amar had the opportunity to fire the first shot. What is the probability that Baron wins the game?

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.

Which of the following are the basic differences between vibration signature and noise signature? 1. Vibration signature is essentially in the frequency range zero to 100 cps whereas noise signature is in the range 20 cps to 3000 cps. 2. Vibration signature has well-defined peaks whereas the noise signal is smeared. 3. The intensities of noise signatures arc much less than that of vibration signatures. 4. Detection of vibration signature calls for a microphone whereas that of noise can do with a pickup. Select the correct answer using the code given below.

There are 5 players of P, Q, R, S, and T. Each of them live on different floors of the five-storey building, which are named as the ground floor, first floor, second floor, third floor and fourth floor. Each of them prefers different sports, such as shot put, javelin throw, kabaddi, long jump and gymnastics but not necessarily in the same order. (i) S likes long jump and lives just below T,who lives on the third floor. (ii) Two players live in between R and Q, R and Q prefer spear throw and shot put respectively. (iii) The player who likes gymnastics lives on the ground floor and lives just below the player who likes the shot put. Who lives on the middle floor of the floors on which T and Q live?
