I want to sample a signal (DC-6Mhz) and store some 500-1000 samples somewhere for later processing.
I don't need to process the samples immediately. I can wait milli seconds for the processing and I only intend to process once every 30 seconds.
Cost is a major factor.
So far I have found a cheap ADC. -AD9280-EB which samples at 32Mhz. excellent!
Now I need to store the first block of samples. I need to grab 1 block of samples every 30 seconds and process the data on a microchip lets say.
What is the best way to do this?
DSP chip? (collect and process at same time)
How can I collect lets say 500-1000 samples in one go? or even higher?
TI has an ADC chip that has a fifo on board but only samples at 6Mhz. Not high enough..
