Hi,
I have to design a low pass filter in VHDL. How can one go about
designing such a filter when the medium is event driven and time
domain based??
How should one decide on the filter characteristics if we just know
the symbol time rate.
If I am using standard VHDL and not AMS is it possible for me to
design such a filter which is used in the recovery loops of receiver?
Most of the references on filter and digital communications refer to
frequency domain analysis. How can I go around this problem?
If the input is a pulse then a low pass filter is an integrate and
dump. However if I have a sampled sine wave how could I design a low
pass filter? Could you please reply and let me know?
I would grealty appreciate your reply.
Looking forward to your replies,
Thanks
Viswanath
PS: I would be needing a filter after the mixing of two sine waves to
filter out the higher frequency components

Hi,

You may want to post your question to comp.dsp news group. I guess what you
are looking for is called digital signal processing.
Take a look at http://www.dspguru.com/

what do you know about vhdl?
