Problem:

An ABCD-to-seven-segment decoder is a combinational circuit that converts a decimal digit in

BCD to an appropriate code for the selection of segments in an indicator used to display the

decimal digit in a familiar form. The seven outputs of the decoder (a, b, c, d, e, f, g) select the

corresponding segments in the display, as shown in Figure 1. The numeric display chosen to

represent the decimal digit is shown in figure 2. The six invalid combinations should result in a

blank display.

Using a truth table and Karnaugh maps, design BCD-to-seven-segment decoder, using minimum

number of gates.

Figure 1 Segment designation.

Figure 2 Numerical designations for display.

Deliverables:

You must deliver a report that contains the following:

1. Derive the truth table based on the description.

2. Simplify it using K-map for each output.

3. Design ABCD-to-seven-segment decoder circuit.
