Abstract

PURPOSE:To obtain the absolute value of an input signal by means of a small circuit constitution by providing an absolute value circuit with a means for inverting the polarity of a bit value under a prescribed condition and outputting the inverted bit value;. CONSTITUTION:The circuit is provided with a means for outputting the value of the least significant bit (LSB) of an input signal as it is and a means for inverting the polarity of a bit value and outputting the inverted bit value when the LSB is '1' and at least one bit out of bits lower than a prescribed bit other than the LSB is '1'. Thereby, when a most significant bit (MSB) is '0', all bits are outputted as they are, and when the LSB is '1', the circuit is functioned similarly to the addition of '1' to an inverted by bit value. Consequently, the absolute value of an input signal can be obtained by the small circuit constitution.
