Inversion of convolution transforms is considered by FIR filters for aperiodic band and time unlimited signals from the perspective attaining maximum accurate inverted waveforms with controllable noise amplification of the filter. The difficulties hampering to gain this goal, such as a lack of knowledge how the digital filter shall deviate from ideal one to produce waveforms as accurately as possible, complexity to choose optimal sampling rate, necessity to sacrifice the accuracy for suppressing noise, etc. are analyzed.
