Abstract

PURPOSE: To quickly analyze the spectrum signal, by simultaneously processing the center frequency and band width of the entire signals in the monitor band through digital processing of spectrum waveform such as electromagnetic waves and vibration.
CONSTITUTION: The input spectrum from the terminal 1 is written in the memory circuit 2 at the first cycle, the content is fed to the maximum detection circuit 3 and the band end detection circuit 4 at the second cycle, the circuit 3 takes the maximum value to the level 1 for the memory at the address corresponding to the maximum value memory 5a, the circuit 4 detects the point haing the level about 6dB lower than the maximum value detected with the circuit 3 and takes the meory at the address corresponding to the band right end memory 5b to level 1. At the third cycle, the band left end memory 5c is written in inversely with the preceding cycle. At the fourth cycle, the frequency band determination circuit 6 is operated, at the fifth cycle, the center frequency is determined from the maximum values in the band determined with the circuit 6, and it is written in the buffer memory 7, and at the sixth cycle, the content is outputted from the terminal 9. Accordingly, the signal is automatically and quickly analyzed.
