Name ______________1. When a HIGH is on the output of the decoding circuit below, what is the binary code appearing on the inputs?0001 Write the Boolean equations for each of the following codes if an active-LOW decoder output is required. The first decode is shown as an example.a. 1101 (A3*A2*A1*A0)b. 11011 (A4.A3*A2*A1*A0)c. 101010 (A5.A4*A3*A2*A1*A0)d. 1110110 - (A6*A5.A4*A3*A2*A1*A0)2. What are the active outputs of a BCD-to-7 segment decoder with an input of 0100?3.1. a, c, f, g3.2. b, c, f, g3.3. b, c, e, f3.4. b, d, e, g3. A 7-segment decoder/driver drives the display below. Using the waveforms shown, determine the sequence of digits that appear on the display. 8 3 5 9 1 4 9 5 6 0 9 8 0 54.
