The 7483 is a 4 bit full adder and a 0 on C will make it act as a subtractor
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.
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.
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.
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) ) ;
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

The country code and area code of Oberndorf an der Melk, Austria is 43, (0)7483.
// 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]); }

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............. │ └─┴─╨───────┘
Is a system whose initial input and any previous input is 0.
Connect both inputs of the NAND gate together to form a single input. Tie one input of the NAND gate to a logic high (Vcc) and connect the other input to the desired input signal.
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.
