PURPOSE:To easily attain circuit integration by decreasing the degree in the increase in a gate number of an adder attended with an increase in a mixing ratio step number. CONSTITUTION:An input output gate number is decreased by reducing a bit length of a data processed by selectors 11,12,..., 18 and adders 19,20,..., 25. Then the degree of the increase in a gate number of the adders 19,20,..., 25 attended with the increase in the step number in a mixing ratio is decreased. Thus, a digital mixer circuit is realized, in which the circuit integration is easily attained. |
