Hi Barry,
thanks for answering.
The level of the burst is about 200-500mV. The "unwanted" burst have 20-50mV amplitude.
I'm sampling 1 bit with a limiter amp and a LVDS logic input. By averaging/overlaying some samples I get a rectangular wave as response of a sine burst. I need to detect the...
Hi!
Sorry for bothering you again. A few hours ago I posted a thread regarding the use of an LVDS Receiver as comparator. Well, you told me why it's not a good idea.
Anyway, it might be more helpful, if I described my problem here:
I need to sample a differential signal and can't use an AD...
Oh well, right, post No 3
Hm, does this mean I should use single ended signal and "compare" it to a reference voltage of 100mV on the LVDS input?
And the receiver can have any offset threshold between 0-100mv? :|
Hi,
let's call the three states A, B, and C :-D
A for >+100mV
B for "noise level"
C for <-100mV
sorry, the formating was poor in my previous post:
output limiter1=high + output limiter2=low equals state A
output limiter1=low + output limiter2=high equals state C
output limiter1=low + output...
Guys, you are fast!
Okay sorry I should have been more specific:
I need to detect three states
>100mV = +1
<100mV =-1
Zero =0
I was hoping to use two LVDS receivers in parallel, with polarity of inputs changed on number two.
The resulting ouputs of the two receivers I would analysze...
Dear all,
Please don't burst out laughing - well you may of course... 8-O
Again one of those silly questions:
Would it be possible to use/abuse a LVDS receiver as window comparator? Basically I need to analyze a signal and decide whether I have high (>100mV), low (<100mV), or something in...
Hi!
I need to realize a time variant filter in simulink/matlab and discovered the function block "Transfer Fcn Direct Form II Time Varying" which should do the job.
Unfortunately I'm completely lost with z-parameters. Can anybody help me here? I need the coefficients for a band pass at frequency...
