PURPOSE:To ensure a prescribed S/N at all times regardless of a signal level by applying direct operating processing to a signal of floating point expression. CONSTITUTION:The 1st signal expressed in a binary number of floating point form is inputted, the code bit of the mantissa part of the 2nd signal in a form expressing the exponent part 2LK by 2L is inverted to form the 3rd signal. The function psij corresponding to each of N-bit information is outputted from a storage device storing 2N sets of functions psij corresponding to the N-bit information of the 3rd signal, the output ...j is operated and the exponent part of the 2nd signal and the operation output introduce the floating point form output signal.
