The Design Of A Seismic Wave Signal Generator Based On The FPGA Series

The seismic wave signal generator based on the FPGA series is designed that can take the place of the actual seismic source,which is not only used to determine the accuracy and precision of detection instruments,but also to debug experiments and adjusts.According to the different needs of the specific seismic wave signal,the signal is transmitted to the specified instruments from the generator.The seismic wave signal generator designed which has simple structure and small size,can produce seismic wave signals moment-to-moment-to-moment reflecting the information of seismic sources.There is a discussion what the configuration circuit of a Cyclone ? EP4CE115F29 chip and the clock circuit design are in the FPGA module;what the design of A/D conversion based on an AD9740 chip is;of the amplitude frequency characteristics of the Butterworth low-pass filter?the Chebyshev low-pass filter and the Bessel low-pass filter;which the solution is;what the performance of the three kinds of basic operational amplifier involving non inverting amplifier circuit?RP amplifier circuit and differential amplifier circuit is;what the amplification of the high speed current feedback operational amplifier circuit based on an AD8009 chip is;what the design of power module based on a LT1764 A series chip is.
