Hi marcus
thanks for immediate reply and your guide was very helpful from my
side ... Now the question is ,
suppose, i have 12 bit 200 mhz adc , and i do not want to reduce my
processing bit , as per the instruction from your side it could be
hard to process in my i5 , 4Gb ddr3 configuration computer and also i am not
aware of the IF bandwidth which might require to make
the bandwidth process instantly ( simultaneously ) . Will gnuradio be able
to support the instantaneous processing of the 100Mhz bandwidth,
I have a bit doubt as i learnt that gnuradio can support 8Mhz only.
Thanks , and i highly apologize if my post is a bit out of track or may be
called a bit illogical ....
Thanks marcus.
