Abstract
A study is made of radix 4 signed-digit arithmetic circuits for high-speed digital filtering. The signed-digit number in a radix 4 is represented by a symmetrical seven-valued digit set left brace plus 3, plus 2, minus 1, minus 2, minus 3 right brace . One of the most important advantages of the signed-digit number system is that carry-propagation is limited to one position to the left during the operation of addition and subtraction, so that a completely parallel execution of arithmetic operations is done in a digital filter. A hardware model for signed-digit circuits in a radix 4 is shown which can be implemented by the current-mode circuit technology.
