Processing Circuit

The signal processing circuit based on FPGA was proposed in the paper, carrying out the function such as programmable signal amplification, adaptive filtering and so on. Among them, the programmable amplifier module was achieved with the programmable gain amplifier in series; Adaptive filter module was implemented with the Butterworth second-order active filter, to change the cutoff frequency of the filter by changing the potentiometer resistance. Experimental results show that the signal processing circuit was applied in the infrared optical system improving the signal to noise ratio of the image effectively.
