Multi-channel signal processing box

Abstract

The invention discloses a multi-channel signal processing box, comprising a box body, and a group successively disposed in the box body and including a signal providing device, a multi-channel signaltransmitting device and a data processing output device. The multi-channel signal transmitting device comprises a plurality of side-by-side branch channel transmitting device. The branch channel transmitting device comprises a delay device and a signal processing device. The signal processing device comprises a signal amplifier connected to a data clock and an A / D converter mounted at the output end of the signal amplifier. The data processing output device includes a programmable gate array device, a data signal processor, and a USB interface that are successively connected. The multi-channelsignal processing box adjusts the delay time of each channel by setting the number of stages of shift registers, effectively removes burrs in the circuit through the reasonable device setting, and has flexible overall structure, good universality, easy maintenance and expansion.

Description

technical field [0001] The invention relates to the field of electronic signal processing, in particular to a multi-channel signal processing box. Background technique [0002] Multi-channel parallel digital signal processing systems play an important role in computer instrumentation, signal detection and other application fields, but traditional multi-channel signal processing devices have some significant shortcomings: (1) Inflexible structure, poor versatility, It is not easy to maintain and expand; (2) The glitch phenomenon in the transmission process of multi-channel signals is serious, and the glitch phenomenon is not handled thoroughly in the prior art, which has a great impact on signal transmission; (3) For common electrical fields A programmable gate array device (FPGA) using SRAM technology, but the data stored in the FPGA used alone will all disappear after power off; shortcoming. Contents of the invention [0003] In order to solve the above existing problem...
