Spectrum Analysis System

The spectrum analysis system, which is based on TMS320F2808, can detect ultrasonic signal in real time. The signal is transformed from time domain to frequency domain by use of FFT. The spectrum graph can be displayed on LCD in real time. The practical results illustrated that this system can analyze the frequency spectrum efficiently with the range of 30kHz~50kHz.
