Hello Alistu,
Okay i got it mate. It is a very very important point you are making here regarding this bandwidth thing . I had never given a thought to it. It means for a system to work properly you must set bandwidth of every component such that the bandwidth of transmitted signals lies in the range of used components. I must look into my design again and set the Bandwidth thing right if there is some correction required.
Thank you so much Alistu for sharing such valuable and important points.
Regards
