Please answer these ten questions! ( one to ten) and explain! Thank you!

1. Given the following two-digit counter with decimal output block diagram which is shown in Figure 14. Decoder Driver Clock Counter 0-99 Decoder/ Driver Decimal Output Block Figure 14. Block diagram of 2-digit counter with decimal output (a)If the 7-segment displays read decimal 85, specify the BCD code between the counter and decoders. 2. Refer to the data sheet for 74147 encoder IC. If only input 7 of the 74147 encoder is low, what is the logic state at each of the four outputs? 3. Refer to the data sheet for 74147 encoder IC. If both inputs 2 and 8 go LOW on the 74147 encoder, what is the logic state at each of the four outputs? 4. Refer to the 7447 IC data sheet and the 7-segment display device. If segments a,c, d, fand g are lit 1. Given the following two-digit counter with decimal output block diagram which is shown in Figure 14.
