    Closed: RTL auto code generation

    Hello,

    I was thinking about an RTL auto code generation based on parsing existing code. Suppose for example that I have a list of modules and each of them has some test ports. I want to be able to...

    [SOLVED]Closed: Re: I Q signals lower sampling rate

    Still don't get it. Supposed our signal has a BW of B as in Fig18 what is the sampling rate of each ADC and waht is the benifit over not-complex down convertion?

    [SOLVED]Closed: Re: I Q signals lower sampling rate

    I don't think this is what he means. After all you can still sample in lower sampling rate than the Nyquist rate if you use undersampling techniques https://en.wikipedia.org/wiki/Undersampling.

    Can you suggest any circuit. As I said the application is cost driven. My design cost less than 0.3 Euros at the moment but I want if possible to go lower than that.

    Closed: Re: Complementary bidirectional switches

    That is true the final swing is from 0-3.3 V but this is not a problem cause the signal is still in margin to be recognised as high or low. On the other hand a switch is maybe a little bit cheaper.
