    • According to embodiments of the present invention, a barcode scanner platform is provided in which the gain of an analog signal representative of a barcode is controlled using a control loop. In embodiments, an MTF detector generates a value (e.g., DC) representative of a low frequency portion (wide or out of optical focus elements) of the analog signal and a second value (e.g., DC) representative of a high frequency portion (narrow elements or in optical focus elements) of the analog signal. The processor uses the first and the second values and a reference amplitude to determine a gain signal. The processor provides the gain signal to an AGC circuit that provides a linear response to the gain signal using matched JFETs. A noise filter can be enabled or disabled based on the first value, the second value, and/or the barcode scanner platform read rate.
    • 根据本发明的实施例,提供了一种条形码扫描器平台,其中使用控制回路来控制代表条形码的模拟信号的增益。 在实施例中,MTF检测器产生代表模拟信号的低频部分(宽或者光学元件的宽度)的值(例如,DC)和代表高频部分(窄的部分)的第二值(例如,DC) 元件或光学聚焦元件)。 处理器使用第一和第二值以及参考幅度来确定增益信号。 处理器向AGC电路提供增益信号,该AGC电路使用匹配的JFET向增益信号提供线性响应。 可以基于第一值,第二值和/或条形码扫描器平台读取速率来启用或禁用噪声滤波器。
