What type of device is shown in the given figure, and what inputs (A3,A2,A1,A0) are required to produce the output levels as shown?

A binary-to-decimal encoder; 0,1,1,1
A decimal-to-binary decoder; 1,1,1,0
A BCD-to-decimal decoder; 0,1,1,1
A decimal-to-BCD encoder; 1,1,1,0

Correct Answer: A BCD-to-decimal decoder; 0,1,1,1

Refer to the display multiplexer given below. The MSD display is blank, while the LSD seems to be OK. The input and output lines to the 74157 and 7449 are checked with a scope and can be seen changing levels. The A input on the 74139 also changes; however, the 0 output on the 74139 is always LOW and the 1 output is always HIGH. The B and EN inputs on the 74139 are always LOW. What could cause the problem and what should be done to correct it?
For the input values (A0–A3, B0–B3, Data Select = 1) given for the circuit given below, what will be indicated on the displays?
The circuit in Figure 9-8 is defective; data is not appearing on the output lines. A check with the scope shows data pulses on the serial data line and multiplex control lines, S0–S2; no parity error is indicated. A further check with a logic probe indicates that Vcc and ground appear to be present. What might be wrong with the circuit?
The device that is an application of SOP logic is a multiplexer.
A demultiplexer is a device that converts some code to a recognizable number or character.
A demultiplexer takes an input and turns it into a binary number.
