hi all, i m currently doing one project on signal processing ..
i have some queries on dsp pls solve them
1) It is stated that " In any distribution , random variables which are independent are uncorrelated but the vice-versa is not true i.e. the variables which tend to be uncorrelated may need not always independent " pls explain me with some practical example..
2) what is the significance of central limit theorem..?
3) what is gauss distribution or normal distribution .......how & where it can be used ..?


THANKS
