[hpsdr] Mercury Receiver Lecture

[Kirk Weedman]

Earlier this year I gave a series of lectures on learning Verilog and 
then on specific topics related to Mercury, Penelope, and Ozy as well as 
Quartus tools, etc..  These were posted on verilog.openhpsdr.org for all 
to download and see.  However, I made some bad mistakes in the 
MercuryReceiver lecture on calculating CIC gains, etc...  I have just 
posted a new MercuryReceiver12_18_2009.ppt on the web page with the 
corrections.  I will need to someday update the video lecture - maybe 
with a voice over to give the correct info.  Currently I am creating a 
new CIC filter that uses RAM resources of the FPGA and plan to make a 
new lecture telling why & how I designed it in detail, including 
detailed timing diagrams.  This will hopefully be used in the multi 
receiver software John Melton is working on.

Anyway, sorry for the misinformation.  Thanks to Phil Harman for 
questioning me about something that got me to looking & thinking about 
what I had done in the lecture.

If anyone has specific questions about what I said vs the new powerpoint 
just let me know.
