    • A laser scanner for reading a bar code having a plurality of bar code elements. The laser scanner includes a digitizer which receives as an input an analog signal from photodetector circuitry and digitizes the analog signal to produce a digital bar code pattern (DBP) signal representative of the bar code. The DBP signal is input to a decoder which reads and decodes the DBP signal thereby decoding the bar code. The digitizer imposes a short duration correction impulse on the DBP signal whenever successive edges of the same polarity are sensed wherein both of the edges are above a threshold level and further wherein the second edge is of greater magnitude than the first edge. When a correction impulse is received on the DBP signal by the decoder, the decoder corrects the DBP signal by removing the first edge and toggling on the second edge.
    • 一种用于读取具有多个条形码元素的条形码的激光扫描器。 激光扫描器包括数字转换器,其接收来自光电检测器电路的模拟信号作为输入,并对模拟信号进行数字化以产生代表条形码的数字条形码模式(DBP)信号。 DBP信号被输入到解码器,该解码器读取并解码DBP信号,从而解码条形码。 数字转换器在感测到相同极性的连续边缘时对DBP信号施加短持续时间校正脉冲,其中两个边缘均高于阈值水平,并且其中第二边缘的幅度大于第一边缘。 当解码器在DBP信号上接收到校正脉冲时,解码器通过去除第一边缘并在第二边缘上切换来校正DBP信号。
