78. A(n) ________ display controls the reflection of available light.
79. The device that places its input data onto one of several outputs is a ________.
80. A(n) ________ has a number of input lines, only one of which is activated at a given time, and produces on N-bit output code, depending on which input is activated.
81. The device shown in below is a ________ and for the waveforms shown in the accompanying diagram, the ________ output at point X will be ________ and all others will be ________.
82. The normal outputs of a magnitude comparator are ________.
83. An eight-line multiplexer must have as inputs ________.
84. Who was the famous poet in the court of Marthandavarma?
85. Which statement below best describes the function of a decoder?
86. One can safely state that the output lines for a demultiplexer are under the direct control of the:
87. A boat goes from river into sea then?
88. Refer to the keyboard encoder in figure (a). Sometimes when the 5 key is pressed, the system attached to the keypad does not respond. The 5 input on the 74147 is monitored with a digital storage scope while repeatedly pressing the 5 key, and the waveform in figure (b) is obtained; the P above the trace indicates the points at which the technician pressed the key. What is most likely wrong with the circuit?
89. The BCD/DEC decoder shown in figure (a) is examined with a logic analyzer and the results are shown in the waveforms in figure (b). What, if anything, is wrong with the circuit?
