computatable efficient lowpass filters?

Started by kungcoccos October 15, 2008
Hi, 
Im looking for computatable efficient lowpass filters. Any suggestions? I
have already read about Wave Digital Filters and the CIC filter (which is a
really great multirate filter btw). 

Thanks in advance

Really? Where have you looked so far? What did you find? What are you trying to accomplish? I don't suppose you have any particular specs to meet, or general signal characteristics, or computational limits, or a processor in mind, or .... ? FIR filter with coefs h(n)=[1 1] is pretty efficient, but it hasn't been real useful for my applications. btw, what exactly do you think a CIC is a really great multirate filter for? Dirk

Make sure you get it in cash, not stock! Dirk

Preferably in something other than USD, too. Rupees would be good. -- % Randy Yates % "...the answer lies within your soul %% Fuquay-Varina, NC % 'cause no one knows which side %%% 919-577-9882 % the coin will fall." %%%% <yates@ieee.org> % 'Big Wheels', *Out of the Blue*, ELO http://www.digitalsignallabs.com

Heard on the news this morning that Iceland is headed for trouble. The currency has dropped some 50% against other currencies and they now have about a month's worth of food supplies on stock. Apparently, no one wants to sell them anything unless they come up with advance payments. They import some 50% of their food, so this might get ugly. Rune

Now Russia wants to buy Island. Perhaps this is just a warm-up exercise for them. Imagine a second crisis hit the US (for example, the credit card balloon). Then it might be interesting for them (or some other Oil backed country) to buy the US, too.

Perestroika in USSA, huh. BTW, in 80-x, when the oil got cheap, the USSA bought Eastern Europe from USSR, and then bought USSR itself. With the oil prices increased, USSR not only bought itself out, but started doing new acquisitions. The so-called modern civilization is just a politically correct name for the oil addiction. VLV

Iceland imports ca 30% of its food (and exports much more than what is consumed in the country) and there are no food shortages. You should not believe everything you read in the press.
