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.

3 Answers

Mask the valid bits and make invalid bits 0. Then do A|B to get the ans

( A & 0xff00 ) | ( B & 0x00ff )

(A&0xffff0000) | (B&0x0000ffff)

Dear Ms.Peters, I read your reply. Unfortunately I personally had a very different and a bad experience even though your statistics might suggest a different picture. Though I appreciate your efforts at replying back, unfortunately I am no more interested in any opportunities in Lahmeyer. Nevertheless, I wish you and the company all the best for future. Less

why is matching required?

2 Answers

Maximum power transfer.

Matching in MOSFET transistor inverters is necessary because the electrons that move in the NMOS transistor move at a faster rate than the holes that move in the PMOS transistor. This means when a signal is received, the NMOS will react before the PMOS. To equalize this, they transistors must be matched (by adjusting their widths) so that their transition times are the same.

1)WAP to count the number of set bits where no of iterations must be equal to the number of set bits, irrespective of the total number of bits. Now make this number of iterations 1/8th. 2) WAP for ceiling function of 2 nos. eg: Ceiling(5/3) should return 3.

2 Answers

int r = n1 / n2 if(n1 % n2) r += 1

2) but ceiling (4/2) should return 2. take care of that case

What are the design considerations for a power supply input filter for a satellite application? Given these considerations, design an input filter for a 100 Watt buck converter. Prioritize small size and low weight. - Input voltage range is nominally 28 VDC (18 VDC to 36 VDC). - Output voltage is 5 VDC. - Switching frequency is 100 kHz. - Assume power return and chassis are isolated > 1 Meg ohm. - Environment is not pressurized Please document and describe your filter and state any assumptions made to complete the assignment.

They want you to take several weeks to do a detailed design and do this in 2 or 3 evenings. Several weeks is greater than several evenings. They have no clue as to how to find good talent. Less

OMG! That's ridiculous. They don't have to hire you if you give them an answer they like, they just use it and you get nothing and like it. Less
