If the memory chip size is 256 x 1 bits, what is the number of chips required to make 1 up 1K byte of memory
1 byte = 8 bits
1K byte = 1024 bits
1K byte = 1024 x 8 bit
Number of chips =
The correct answer is: 32
The number 6.25 in the decimal notation, when converted to the binary notation will read as ?
Hence, 6 =110
Now 0.25 x 2 = 0.50 → 0
0.50 x 2 = 1.00 → 1
0.00 x 2 = 0 → 0
Hence, 0.25 = 0.010 →1
Hence (6.25)_{2} = 110.010
The correct answer is: 110.01
What must be the output if A = 1 , B = 0, C = 1 ?
Hence, output = 1
The correct answer is: 1
In the given circuit, if the inputs A = B = 0, then what is the output of D ?
A = B = 0
Logic states of C and D will be 0, 0
The correct answer is: 0
The function F generated by the logic network shown gives what output for
Hence gives
The correct answer is: 0
The correct answer is: 0
When both the input signals A and B of the NOR & NAND gate are connected together, The output of the resultant circuit will be equivalent to
When both the input signals A and B of NOR & NAND gate are connected together, we have one common input connection hence the resultant output will be NOT gated.
If two input terminals of NAND gate are shorted, then the output for both the input being zero is ?
If A and B are joined, then
This behaves like a NOT gate.
The correct answer is: 1
An OPAMP is connected in a circuit with a Zener diode as shown in the figure. The value of resistance R in kfl for obtaining a regulated output V_{o} = 9 V is: (Specify your answer to two digits after the decimal point.)
For the Boolean expression what will output for A= 1, B = 1, C = 0 ?
The correct answer is: 0
