for the first question, I think it's not a software issue, because the software can not know the existence of hub, the only problem will be the network wire, it's quality is not good enough.
resolution bandwidth of spectrum analyzer
lets take an example, if the resolution bandwidth is 100khz, video bandwidth is 10khz, then how to tune the video filter to make this bandwidth? I know the Video filter is to make the spectrum smooth, but how this filter be related to a bandwidth? I...
spectrum video bandwidth
Still confused after refer to the appnote , Video filter is applied to the spectrum waveform , then what does the bandwidth parameter stand for?
video filter bandwidth
I feel a little confused, the Video filter is applied to the spectrum waveform ( not the time domain), right? then how can you tell " the video bandwidth is 100kHz" (for example) ? What is the physical meaning of the video filter's output?
bcd routine in c
A DEC number is expressed as
Dn*10^n+...D2*10^2+D1*10^1+D0*10^0
divide the hex number with 10, the remainder is D0, then use 10 to divide the quotient again, the new remainder is D1, repeat this process, until you get all the digit. It's quite easy to implement this in C, you...
You'd better avoid calling C function in ASM file, if need, only call the C function without input parameters, cause the input parameters are stored in registers or memory depending on the compiler. To call C function, it's usually call _func for func() routine, maybe you also should declare the...
