Hi,
I am studying signal processing. On this matter, there exists signals at 10kH (audio signals), but there exists signals on the 1GHz frequency. Suppose I want to acquire and process this high frequency band signals (1GHz signals). Suppose also I have an analogical to digital converter (ADC) operating at this 1GHz rate (i.e. the ADC is a 1 giga samples per second). I will need a microprocessor in order to digital processing the samples signal, and so my doubt occur at this point: there is not available at the market a >1GHz clock micrcontroller or FPGA.
So, althougth it is possible to have a 1GSPS ADC, how could I buffer to the memory these sampled data at the same ADC frequency, in order to have a set of data sampled at 1GHz?
In other words, is it possible and is it the best practice, to have an ADC synchronously connected to a kind of memory (it could not be a DDR memory since DDR is 333MHz) both and so sampling and on-line storing in the memory data at 1GHz?
Hope I could be clear explaining my doubt.
Thank you!
Nathan.
