How many 2-input and gates can replace n-input and gate Does that apply for nand gates as well?
for a two input gate to represent as an n-input gate excatly n-1 two input gates are required. this implies that for a two input OR gate to represent a four input OR gate exactly three two input OR gates are required let F is =a+b+c+d =(((a+b)+c)+d) =((a+b)+(c+d)) in both the above cases + is used three times so three two input OR gates make a four input OR gates. This discussion doesnot hold good for NAND gates an example can illlustrate the reson:- take F=(a.b.c.d)'=a'+b'+c'+d' --------------------------->(1) (this is obtained by a four input NAND gate) let us take this in the manner we did it for an OR gate and we will then verify the result. =((a.b)'(c.d)')' =((a'+b').(c'+d'))' =(a'+b')'+(c'+d')' =ab+cd <------------------------(2) (1)is not equal to (2) so we can say that a NAND gate cannot be replaced in the manner as OR gate is replaced
Design and draw a combinational circuit using AND-OR-NOT gates that accepts 4 input bits and produces two bit output the first of the two bits is set to 1 if the number of 1s in the input is even?
Design and draw a combinational circuit using AND-OR-NOT gates that accepts 4 input bits, and produces two bit output; the first of the two bits is set to 1 if the number of 1's in the input is even; and the second of the output bit is set to 1 if the input have 3 or more (all four) 1 bits.
Draw logic diagram of two to four line decoder using nor gates only with enable input?
draw logical diagram 2 to 4 line decoder with nor gates only
What is an 7402 ic?
A: It is a 14 pins dual in line quadruple 2 input positive NOR Gates. It BELONG TO THE 74XX family of IC
What is the input impedance of an ideal voltage op-amp?
To get all the voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Why the internal resistance should be high in operational amplifiers?
High input impedance implements the operation of the external feedback circuitry (e.g. diff. amplifiers vs. comparators).
What is the flag input of AND gate?
To produce a 3-input OR gate when only 2-input OR gates are available: Use 3 OR gates Inputs to Gate A are input 1 and input 2 Input to Gate B is input 3 (if 2 inputs are necessary, include input...
Difference between internal and external inputs?
internal input is the one where we give inputs as well and external input is the clock input
What are the basic building blocks of digital ICs?
Usually NAND gates or NOR gates, as these are the universal gates from which all other gates, flipflops, registers, etc. can be built. - - - - - There are four basic building blocks: gates with more than one input: AND: output high if all inputs high OR: output high if any input high gates with one input: buffers: output high if input high; these are used at the ends of long wiring runs so following gates get clear signals--IOW, they're amplifiers inverters: output low if input high A NAND gate is an AND with an inverter follower, and a NOR is an OR with an inverter follower.
Why XOR and XNOR gate is not known as universal gates?
All other logic gates can be made using XOR and XNOR, but to get NOT, you need to do (input) XOR 1 or (input) XNOR 0, but with NAND, you don't need 1: (input) NAND (input).
What is a binary flip flop?
A binary flip flop is a collection of 4 NAND gates arranged in specific circuit to allow it preserve state. The first two NAND gates use an external voltage as their first input and themselves as their second input; where as the second set of NAND gates use the first pair of gates output as their first input, and themselves as their second input.
Why auditory response is quicker than visual?
Because less neural processing is required and the nerve "circuitry" is much simpler for auditory input than for visual input.

Drawback of dc dc converter with out electrical isolation?
A:The circuitry that follows will be sitting at the input line potential.
Do 2 input nor gates form a complete set of logic gates?
nor as well as nand gate are universal gates they both can be used as a complete set of logic gates
What is square wave input?
It is a square shape of the wave applied at the input of the circuitry> ANSWER: A square wave is basically two rectangular power input It is called square to differentiate from other sources triangular sawtooth and so forth.
Why would you need to convert a string to a numeric data type?
For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.
