Embodiment Construction
[0020] Such as figure 1 , 2 As shown, the present invention includes: a first differential square wave generation module 3, a second differential square wave generation module 4, a first shaping sharpening module 5, a second shaping sharpening module 6, a digital sampling module 7, and a digital filtering control module 8. A digital filter module 9 and a communication module 10 . The process of signal transmission and processing is as follows: figure 2 As shown, specifically:
[0021] After a signal 1 passes through the first differential square wave generation module 3, it is superimposed with a 2k square wave, and the superimposed signal is transmitted to the first shaping and sharpening module 5, which is used for the first shaping and sharpening module 5. Shaping and precise edge sharpening are performed, and the first shaping and sharpening module 5 generates a synchronous narrow pulse, and then the narrow pulse is transmitted to the digital sampling module 7 .
