WebThere is a parameter Image Frequency is configured as -1MHz during the testing, and they found 2426MHz and 2476MHz can not pass the testing. Do you have any suggestion on that? and does the Image Frequency value -1MHz is correct? we found it in CC2564B datasheet as below. thanks. LEON over 4 years ago 0 Hari Nagalla over 4 years ago WebThespectrogram is a tool that allows us to see the frequency properties of a signal as they change over time. The spectrogram works by taking multiple DFTs over small, overlapping segments1of a signal. The magnitudes of the resulting DFTs are then combined into a matrix and displayed as an image. Figure 7.1 shows the spectrogram of a DTMF signal. philips 805 65 zoll
