| Abstract: | This system was designed mainly with MCU and FPGA composed of four blocks: programmable amplifier,adjustable filter,amplitude frequency characteristic analyzer,control and show part.The gain of the amplifier is from 0 to 60 dB with step 10 dB.Three kinds of filters including high pass,low pass and the oval filter were integrated in a single FPGA,and the parameter of the filters and the amplifier can be set by keyboard and displayed on LCD.The amplitude frequency characteristic analyzer can display the frequ... |
