ABSTRACT:
A low pass filter that approximates a Gaussian transfer function filters the analog bar code signal prior to digitization is used to smooth the bar code signal. The Gaussian filter has a transfer function that compensates for beam distortion close in to the bar code scanner. The smoothed bar code signal is provided to the digitizer to improve the efficiency with which the bar code signal can be digitized.
