Abstract
A circuit divides pulse code modulation (PCM) samples in D2 format. An exponent subtractor provides the difference of the exponents of the two numbers. A mantissa multiplier circuit determines the quotient by multiplying the mantissa of the PCM sample by an inverted divider. A sign generator provides a sign value for the resultant quotient of the two numbers. A normalizer circuit ensures that the quotient mantissa has a predetermined range of values.
