Q.1

Most demultiplexers facilitate which of the following?

  • decimal to hexadecimal
  • single input, multiple outputs
  • ac to dc
  • odd parity to even parity
Q.2

One application of a digital multiplexer is to facilitate:

  • code conversion
  • parity checking
  • parallel-to-serial data conversion
  • data generation
Q.3

Select one of the following statements that best describes the parity method of error detection:

  • Parity checking is best suited for detecting single-bit errors in transmitted codes.
  • Parity checking is best suited for detecting double-bit errors that occur during the transmission of codes from one location to another.
  • Parity checking is not suitable for detecting single-bit errors in transmitted codes.
  • Parity checking is capable of detecting and correcting errors in transmitted codes.
Q.4

A circuit that responds to a specific set of signals to produce a related digital signal output is called a(n):

  • BCD matrix
  • display driver
  • encoder
  • decoder
Q.5

A multiplexed display:

  • accepts data inputs from one line and passes this data to multiple output lines
  • uses one display to present two or more pieces of information
  • accepts data inputs from multiple lines and passes this data to multiple output lines
  • accepts data inputs from several lines and multiplexes this input data to four BCD lines
