Problems solved by technology

[0002] With the development of computer technology, computer technology is widely used in the field of signal processing technology. When the existing computer processes digital signals, it can only process the signal of one channel in real time. When there are multiple signals in the intermediate frequency band, time-sharing is required. processing, cannot process multiple signals at the same time
Since the speed of the data stream after ADC sampling is higher than the frequency of the PCI bus, the data cannot be processed continuously; if the acquisition card is equipped with a large-capacity memory, it will occupy too much CPU resources

The method comprises the following steps: S1, acquiring data by using a multi-channel data acquisition module; s2, processingand amplifying the acquired data through a signal amplifier and a calibration compensation processor; s3, converting the processed data signal into a digital signal through an analog-to-digital converter; s4, processing the digital signal obtained in the S3 through a digital signal processor and a field programmable gate array device; and S5, transmitting the processed signal through a communication module. The method can obviously improve the processing efficiency and accuracy.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and more specifically relates to a multi-channel digital signal processing method. Background technique [0002] With the development of computer technology, computer technology is widely used in the field of signal processing technology. When the existing computer processes digital signals, it can only process the signal of one channel in real time. When there are multiple signals in the intermediate frequency band, time-sharing is required. Processing, cannot process multiple signals at the same time. Because the speed of the data flow after ADC sampling is higher than the PCI bus frequency, the data cannot be processed continuously; if the acquisition card is configured with a large-capacity memory, it will occupy too much CPU resources. Contents of the invention [0003] The object of the present invention is to propose a multi-channel digital signal processing method in order to...
