Re: Papers for UPCL Written Test

You are asking to UPPCL Electronics Written Test Question Paper. Here I am uploading a file that contains the UPPCL Electronics Written Test Question Paper. You can download this from here. Here I am also providing you some content t of the file. This is as follows:

1. For one of the following conditions, clocked J-K flip-flop can be used as DIVIDE BY 2 circuit where the pulse train to be divided is applied at clock input.
a) J = 1, k = 1 and the flip- flop should have active HIGH inputs
b) J = 1, k = 1 and the flip- flop should have active LOW inputs
c) J = 0, k = 0 and the flip- flop should have active HIGH inputs
d) J = 1, k = 1 and the flip- flop should be a negative edge triggered one

2. Number of comparators needed to build a 6-bit simultaneous A/D converter is
a) 63 b) 64 c) 7 d) 6

3. The AID converter used in a digital voltmeter could be (1) successive approximation type (2) Flash converter type (3) Dual slope converter type. The correct sequence in the increasing order of their conversion time taken is
a) 1, 2, 3 b) 2, 1, 3
c) 3, 2, 1 d) 3, 1, 2

4. Which of the following binary number is equal to octal number 66.3
a) 101101.100 b) 1101111.111
C) 111111.1111 d) 110110.011
