The onescount of a multi-bit signal is the total number of true signals there are in that multi-bit signal, where the output count is given in the 2-bit binary encoding listed above. thus, the onescount of "000" is "00" (representing the value zero), and the onescount of "101" is "10" (representing the value two). design the simplest sum-of-products equations possible that will return the onescount of a 3-bit input z[2: 0]
