You have 2 buckets in a room and one bucket has 17 Red balls, 19 Green Balls, 21 Blue Balls, 23 Yellow Balls. You are blindfolded and you need to pick one ball at a time and put in the bucket#2. You should stop at a point where you are confident that the color of the ball you are putting in already exists in the bucket#2. When would you stop?
What is difference between source coding, channel coding and modulation?
1. MIMO Systems- explain the benefits of 2Tx/1RX vs 1Tx/2Rx 2. 10 wires with each having 2 ends are inside a bag. 2 ends can be connected to form 1 notch. The total number of possible notices are 1 to 10. Find the expected value of possible number of notches. Explain the process. 3. Given a PDF with an exponential distribution of lambda(e^-lambda x) explain how to find lambda given ten independent observation points. 4. given a complex system of -1 to +1 KHz, determine the Nyquist rate and what under what conditions will aliasing occur. If the bandwidth was triangular shaped, what will the resulting shape be when Fs is 2 KHz.
Swap two numbers without using a temporary variable
A and B are 32 bit numbers with first 16 bits valid in A and next 16 bits valid in B. (The non-valid bits aren't necessarily 0). WAP that adds A and B without using arithmetic operator.
convolution of a positive signal with itself many number of times will result in what kind of waveform?
All about resume, why SCFDMA in uplink, PHFICH channel frequencies, what happens in MRC, LTE call procedure.
You have 8 balls. 7 are 150 grams and 1 is 152 grams. With minimum (2) iterations find out the heaviest ball with the weighing machine.
