Fig shows a decoder circuit hex_to_BCD that decodes a 4-bit binary number \( \mathrm{d}[3: 0] \) into two binary coded decimal (BCD) digits: disp_1[6:0] and disp_0[6:0], which drive two 7segment displays. The leftmost display (disp_1) should either be blank or shows the digit 1. For example, if \( d[3: 0]=4^{\prime} \) b0101, the value 5 is displayed; if \( d[3: 0]=4^{\prime} b 1100 \), the value 12 is displayed. Desgin Gate level Circuit.
