Function of ic 7490 decade counter?
The function of an IC 7490 Decade Counter, which is a computer chip, is to pin cycles 0 to 9 through QA, QB, QC and QD which are 4 bits in a binary number. The IC 7490 Decade Counter produces an output pulse for every ten input pulses.
What is ic 74150?
It is a data selector. There are 16 digital input lines, 4-bit decoder, strobe and output pin. So you put a 4-bit binary number from 0-15 into ABCD bits and the corresponding input value is found on output at the strobe time.
Working principle of ic 4017?
The IC 4017 works as a digital counter and decoding unit. The circuit can count from 0 to 10 and has 16 prongs with LEDs that light up as each prong is being utilized.
How do you write the Boolean expression for XOR gate?
For 2-input EX-OR gate, if one input is A, the other input is B, and the output is Y. Then the Boolean expression for EX-OR (XOR) function (gate) is Y=A⊕B The output Y is true if either input A or if input B is true, but not both.Y= ( (A and NOT B) or (NOT A and B) ) ;
Why is 5 volt assigned to logic 1 state and 0 assigned to ground?
Ground is a base point in every circuit.we define it's potential to 0.so GND=0 Volts. We know that logical circuits build up with transistors and use those in saturation mode. in saturation mode we need 5 volts voltage in input to we have this mode.5 volt voltage is IC working voltage(Vcc) too. so 3-5 volt is 1 logic
How many NOT gates are needed to turn on a memory IC if the address 10000001 is at the CE input of the chip?
To turn on a memory IC with an active-low Chip Enable (CE) input, you need to ensure that the CE signal is low (0) when the address 10000001 is provided. If the address corresponds to a high signal (1), one NOT gate is needed to invert the address signal to a low signal (0) for the CE input. Therefore, only one NOT gate is required to achieve this.

What is the country code and area code of Oberndorf an der Melk Austria?
The country code and area code of Oberndorf an der Melk, Austria is 43, (0)7483.
Why is 7475 IC chip is called a latch?
The 7475 IC chip is called a latch because it is a type of digital storage device that holds a binary state (0 or 1) until it is changed by an input signal. Specifically, it is a D-type latch that captures the value of the input data line when the enable signal is activated, maintaining that value even when the input changes, thus "latching" the data. This behavior allows it to store information temporarily, making it useful in various applications in digital circuits.
To display an input string vertically by c?
// get input char input[256]; gets(input); // print one character on each line int i; for(i = 0; input[i] != '\0'; ++i) { printf("%c\n", input[i]); }

When A 0 B 0 C 1 then in 2 input logic gate you get - - gate?
input outA B A XNOR B 0 0 1 0 1 0 1 0 0 1 1 1
Determine the highest of the three input numbers using flowchart?
(start) /a=0 c=0\ \b=0 / /input a/ /input b/ /input c/ /a>b\ no /b>c\ yes /display b/ -> (a) \ / \ / yes no /a>c\ no /display c/ -> (a) \ / yes /display a/ <- (a) (end)
Why is the and gate called the and gate?
Because if input A *and* input B is true, then the output is true! Truth table of AND gate: ┌─┬─╥───────┐ │A│B║Q (Output)│ ├─┼─╫───────┤ │0│0║0..............│ ├─┼─╫───────┤ │0│1║0............. │ ├─┼─╫───────┤ │1│0║0............. │ ├─┼─╫───────┤ │1│1║1............. │ └─┴─╨───────┘
What is relaxed system?
Is a system whose initial input and any previous input is 0.
What is a not gate in electronics?
A not gate is a logical gate which inverts a digital signal. If the input to a not gate is 1, then the output will be 0. If the input is 0, then the output will be 1.
