Design Introduction
We designed a portable vibration spectrum analyzer based on the Altera Nios II soft core processor
and FPGA. The instrument is used in fault monitoring and diagnosis of rotary machines, which are used
in battle tanks, armored cars, and vehicle engines. The operation of these vehicles may be affected by
abnormal vibrations for different reasons, including serious accidents that may lower fighting strength
and productivity. To solve the vibration diagnostics problem, we
