Methods for the minimization of truncation- error in the case of an mrt

摘要

The invention relates to devices and method for the truncation (t, t) of signal data (sd) in a system (101) of a mrt, in particular in a demodulator (117), characterized in that, in the system (101) is a multiple truncation (t, t) of signal data (sd) on its path (m – m3, a1, a3) between the input (e) and output (a) of the system (101) for the respective reduction of the bit width of signal data (sd) is provided, and that in the case of only a part (t3, t4, t5, t6, t8, t9, t10, t11, t13, t14, t15, t16) of the multiple truncations (t, t) to truncierende signal data in each case in front of or after their truncation (t3, t4, t5, t6, t8, t9, t10, t11, t13, t14, t15, t16) is inverted (inv1 – 12; coeff) are.
