- 101. Example From Figure, identify the row and column of the pressed key for each of the following. (a) D3 – D0 = 1110 for the row, D3 – D0 = 1011 for the column (b) D3 – D0 = 1101 for the row, D3 – D0 = 0111 for the column Solution : From Figure, the row and column can be used to identify the key. (a) The row belongs to D0 and the column belongs to D2; therefore, key number 2 was pressed. (b) The row belongs to D1 and the column belongs to D3; therefore key number 7 is pressed
