The variable frequency synthetic vessel which installs the factor variable interpolation vessel and the factor variable interpolation vessel

摘要

The said factor variable interpolation vessel N the serial has the N next sigma delta modulator which has the sigma delta step which is connected fraction in the factor variable interpolation vessel in order to interpolate to the variable digital mark which displays fraction, here, N is integer of 2 or more, as for the sigma delta modulator, you respond to the molecule and denominator of fraction in order to output the variable digital mark, as for value of the molecule and denominator selection the factor variable interpolation vessel which features that it is possible.
