A calculation circuit for the division of a fixed-point input signal comprising a sequence of digital data values having a width of n bits by an adjustable division factor 2a for the purpose of generating a divided fixed-point output signal, having a signal input (2) for applying the data value sequence of the fixed-point input signal, a first addition circuit (6), which adds the digital data value present at the signal input (2) to a data value buffer-stored in a register (33) to form a digital first summation data value having a width of max (n, a+1)+1 bits, a shift circuit (11) which shifts the first summation data value present by a data bits toward the right, with the result that the max (n, a+1)-a+1 more significant data bits of the first summation data value are output at an output of the shift circuit (11), a logic circuit (16), which, as a function of the sign of the first summation data value, logically ANDs the a less significant data bits of the first summation data value with a logic combination data value, or logically Ors them with the inverted logical combination data value, and outputs them to the register (33) for buffer-storage of the logically combined data value (dv1, dv2), a second addition circuit (37), which, as a function of the sign of the first summation data value adds the data value output by the shift circuit (11) to a value one for eliminating the DC signal component to form a second summation data value, and having a signal output for outputting the sequence of the second summation data values as divided fixed-point output signal.
