    DIWEI company, anybody heard of it?

    Hello all , I came across (on the web) a gsm module that looked interesting, at least from a price-wise perspective. It is the m5200 from DIWEI - which I suspect to be a china based company. I am trying to find its data sheet not to mention the company website but so far nothing. Has anybody...

    stability criteria of system/circuit - quandary

    Hello all, I have a question concerning the stability criteria of system/circuit that always bothered me. Q: A bode plot where the phase response toggles from 180 to -90 (or anything negative for that matter) while the gain response remains above 0dB is representative of an...

    calibre DRC *.cal file syntax - please help

    calibre syntax Hello all, I recently started using the calibre DRC verification tool. It works great and I like it. However, I can not seem to find an online source describing the syntax that is used in the *.cal rule files. I know it is fairly easy to read and reverse-engineer when you have...

    Failed to start cdsdoc, please help !!!

    cdsdoc starting viewer Hello all (again), I changed the LD_ASSUME_KERNEL in the cdsdoc file to the the value of my kernel and it still it doesn't work. I still get the message that libnsl.so.1 cannot be opened when I double-click on a particular help topic. I've been on this bug for a week now...

    FIR Filter limitations (or not) ?

    Hello Rajan, Few questions for you. >so no matter when u pass it through a FIR LP filter or HP etc.. its only the response from 0 to >Fs/2 that matters... Is it because both the response of the digital filter and the digital’s signal frequency spectrum are periodical about a period of Fs; so...

    FIR Filter limitations (or not) ?

    Hello, I am quite new to the field of digital FIR filters (I always worked with the old-fashionned analog ones, but I digress). There is an important aspect to FIR filters that eludes me: A low pass digital FIR filter filters out all frequencies in the stopband (to the set attenuation)...
