First there is a written test and then interview. Written test consists of 4 secetions Digital--30marks Communications---20marks Computer---20marks Aptitude--30marks Each questions carry weightage differently Digital: It includes both STLD ,VHDL and Microprocesers. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1)Design 3:1 multiplexer&nbsp; using one tri-state buffer,AND gates and NOT gates. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2)The no of 2-input XOR gates required to design 19-inprt XOR gate? &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3)A 26Kbyte memory,there is memory it contains 12 adderss lines and 4 bit data&nbsp; bus,the number of these type of memories required to design 26Kbyte memory? &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4)Write a VHDL or Verilog HDL code for &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; input:a,clock,reset &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; output:out &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; out is assigned to 1 when a is ,1, for two clock cycles. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 5)what is the output of following fig.100ps is the delay for XOR gate and 50ps for AND gate .all +ve and -ve edges start at boundaries of nanoseconds.(actually the output of fig is&nbsp; A(B(notC)+(not B)C) ,and the waveforms are given). &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 6)design forwhich the output is 10MHz clock,input to that circuit is 30MHz. Communications: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 7)&nbsp; What is shonan,s theorem? &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 8)X is Gaussianly distribuyed signal &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; a)p(X&lt;=infinte)=? &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; b)X is zreo mean and a unit variance random variable,them find the mean and variance of y &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; y=2X+5; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 9)because of error 000 is coded insted of 0 ,111insted of 1.then what is the error correction and error detection capability of the system? &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 10)A deterministic signal whose pdf is given then we have to find the minimum sampling frequency needed ? Computers: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 11)one question on bit rate.....(i didn,t rember exactly) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 12)what is the application os MS world and Msperfect application is? &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 13)write a c code for factrial using recursion. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 14)some statements are given like &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; putup::then lift the pen move accordingly without drawing aline, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; FD N::move forward (N distance) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; LD N:: move left at an angle of 90 degrees then move N &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; RD N::move right at an angle of 90 degrees then move&nbsp; N &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; putdown::draw alin following instructions what is the output of following code putdown FD 10 putup LD 1&nbsp; FD 2 putdown RD 8 so on like is.... &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 13)what is the output &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int a[10]={0,1,2,3,4,5,6,7,8}; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int *p=a; printf("%d\n",*p++); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 14)two genaral knowledge questions.. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 15)what is expansion of GMSK? &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 16)find out the 5 digit number in that 4th digit is 4 nore than the second digit ,3rd digit is&nbsp; 3 less the 2nd digit andfirst is 3 times the last digit?
