Q. |
## Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function. |

A. | using a as the control, when a = 0, x is the same as b. when a = 1, x is the same as b. |

B. | using a as the control, when a = 0, x is the same as b. when a = 1, x is the inverse of b. |

C. | using a as the control, when a = 0, x is the inverse of b. when a = 1, x is the same as b. |

D. | using a as the control, when a = 0, x is the inverse of b. when a = 1, x is the inverse of b. |

Answer» B. using a as the control, when a = 0, x is the same as b. when a = 1, x is the inverse of b. |

- The gate is an OR gate followed by a NOT gate.
- Refer to the given figures (a) and (b). A logic analyzer is used to check the circuit in figure (a) and displays the waveforms shown in figure (b). The actual analyzer display shows all four data outputs, Q0-Q3. The analyzer's cursor is placed at position X and all four of the data output lines show a LOW level output. What is wrong, if anything, with the circuit?
- The truth table for an S-R flip-flop has how many VALID entries?
- A logic circuit that provides a HIGH output if one input or the other input, but not both, is HIGH, is a(n):
- The maximum noise voltage that may appear at the input of a logic gate without changing the logical state of its output is termed as
- Which type of gate can be used to add two bits?
- A bidirectional 4-bit shift register is storing the nibble 1101. Its input is HIGH. The nibble 1011 is waiting to be entered on the serial data-input line. After three clock pulses, the shift register is storing
- An OR gate can be imagined as
- The Output is LOW if any one of the inputs is HIGH in case of a gate.
- The output of an AND gate is LOW ________.
