Title: The real time spectrum analyzer
Inventor: CHOU YUAN-FANG
IPC: G01R23/00
Filed: 2001-12-31
Granted: 2003-09-01
Abstract: This invention is the real time spectrum analyzer. The signals received from targeted ones via the receiver are treated by following steps: passing through a low pass filter, amplifying, modulating with the mixer, and passing through the band pass filter. The transducer converts the treated signals into the type that can be recognized by the channel filter. Then, the signal spectrum can be obtained by collecting and exporting all the individual result from the filtering sets of the channel filter. The procedure mentioned above is carried out in time domain. Even though the targeted signals change randomly, the analyzer will show the real time information. Furthermore, the number of filtering sets determines that of the channels. The design of the mixer using promotes reducing the size of the channel filter in order to adapt to the micromachining techniques and integrate with the IC processing, leading to mass production and cost reducing.
